The State Board of Registration for the Healing Arts (the Board) initiated a disciplinary complaint against Dr. Edward MeDonagh primarily alleging that he vio*149lated section 334.100,1 a part of the Missouri Healing Arts Practice Act, through his representations regarding and use of chelation therapy in the treatment of patients with vascular disease. The Administrative Hearing Commission (AHC) found no cause to discipline Dr. McDo-nagh’s medical license. The circuit court affirmed the AHC’s decision. The Board appeals, alleging the AHC erred by failing to apply the standard for admission of expert testimony set out in Frye v. United States, 293 F. 1013 (D.C.Cir.1923), and that the testimony of Dr. McDonagh’s experts should have been excluded.
This Court reaffirms its holding in Lasky v. Union Electric Co., 936 S.W.2d 797 (Mo. banc 1997), that the standard for the admission of expert testimony in civil cases is that set forth in section 490.065. As discussed herein, this is also the standard to be applied in administrative cases. To the extent that civil cases decided since Lasky apply Frye or some other standard, they are incorrect and should no longer be followed. Section 490.065.3 requires that the facts and data on which an expert relies must be those reasonably relied on by experts in the relevant field. Here, the relevant field is physicians treating persons with vascular disease. Because the AHC failed to properly apply this standard, this Court reverses the circuit court’s judgment and remands the case. On remand, the circuit court should remand to the AHC for reconsideration of the AHC’s decision in light of this standard.
This Court also remands for reconsideration of the issue whether Dr. McDonagh committed repeated negligence because his experts did not identify the standard of care by which they judged his treatment of his patients and it appears the AHC judged his conduct by reference to the treatment advocated by other doctors using chelation therapy. Under section 334.100.2(5), the AHC should have judged the conduct by the standard of care of those treating patients with vascular disease.
Because the principles stated herein may also affect the AHC’s determination of the remaining issues regarding record keeping, testing, and misrepresentation, this Court remands the case in its entirety for reconsideration in light of this opinion.2
I. FACTUAL AND PROCEDURAL BACKGROUND
The Board is authorized by section 334.120.1 to register, license, and supervise physicians and surgeons practicing in Missouri. The Board licensed Dr. McDonagh, D.O., as an osteopathic physician and surgeon in 1961. Soon after becoming licensed, he began employing alternative medical treatments in his family practice, including EDTA3 chelation therapy to treat atherosclerosis and other diseases. He also became certified by the American Board of Chelation Therapy, and has conducted research and written extensively on the use of this therapy.
A. Regulation of Chelation Therapy by the Board.
Chelation therapy has been approved by the federal Food and Drug Administration (FDA) only as a means for the removal of *150heavy metals from the body. However, non-FDA-approved, or “off-label,” use of medications by physicians is not prohibited by the FDA and is generally accepted in the medical profession. See 21 U.S.C. Sec. 396 (2000); Buckman Co. v. Plaintiffs’ Legal Comm., 531 U.S. 341, 350-51 & n. 5, 121 S.Ct. 1012, 148 L.Ed.2d 854 (2001). Approximately 1,000 physicians in the United States engage in the off-label use of chelation therapy to treat atherosclerosis and other vascular conditions.4 Of these 1,000 United States-based physicians, 750 belong to the American College for Advancement in Medicine (ACAM), which has 1,000 members worldwide and which endorsed chelation therapy as a valid course of treatment for occlusive vascular and degenerative diseases associated with aging.5 To that end, ACAM developed a protocol, followed by Dr. McDo-nagh, for using chelation therapy to treat such diseases.
In 1989, the Board made an in-depth study of the efficacy of chelation therapy, but did not thereafter adopt any rules, regulations, or position papers on the use of this therapy. Then, in 1992 and 1994, two controlled studies were published that suggested that chelation therapy was ineffective in treating vascular disease.6 Dr. McDonagh disputes the validity of these studies. But, after the publication of the studies, the American Medical Association (AMA) adopted a position statement on chelation therapy, declaring that: “(1) [t]here is no scientific documentation that the use of chelation therapy is effective in the treatment of cardiovascular disease, atherosclerosis, rheumatoid arthritis, and cancer”; (2) chelation therapy proponents should conduct controlled studies and adhere to FDA research guidelines if they want the therapy to be accepted more broadly; and (3) “[t]he AMA believes that chelation therapy for atherosclerosis is an experimental process without proven efficacy.” AMA, AMA Policy Compendium H-175.994, H-175.997 (1994).
In spite of these developments, neither the FDA, the AMA, or the Board banned the use of chelation therapy to treat vascular disease, and Dr. McDonagh continued to prescribe and administer the therapy in his practice.
Effective October 30, 2001, the Board adopted, a rule stating that chelation therapy was of no medical value but that it would not seek to discipline a physician for using it on a patient from whom appropriate informed consent is received:
*151(1) Pursuant to authority granted to the board by section 334.100.2(4)(f), RSMo, the board declares the use of ethyline-diaminetetracetic acid (EDTA) chelation on a patient is of no medical or osteopathic value except for those uses approved by the Food and Drug Administration (FDA) by federal regulation.
(2) The board shall not seek disciplinary action against a licensee based solely upon a non-approved use of EDTA che-lation if the licensee has the patient sign the Informed Consent for EDTA Chelation Therapy form, included herein, before beginning the non-approved use of EDTA chelation on a patient.
4 CSR 150-2.165.
B. Complaints Against Dr. McDo-nagh.
In 1994, seven years prior to the adoption of 4 CSR 150-2.165, and shortly after the two noted controlled studies, the Board filed a complaint against Dr. McDonagh arising out of two inquiries regarding his use of chelation therapy. This complaint was later dismissed without prejudice. In 1996, the Board filed a thirteen-count complaint alleging cause to discipline Dr. McDonagh’s medical license for violating section 334.1007 by, among other things: endangering the health of patients through the inappropriate provision of chelation therapy; misrepresenting the efficacy of this therapy for atherosclerosis and other diseases; conducting unnecessary testing and treatment in some instances, and insufficient testing and treatment in others; and failing to maintain adequate medical records.8
Dr. McDonagh denied that his treatments endangered his patients, denied using inappropriate testing or treatment, and denied inadequate record keeping. He also denied making misrepresentations to patients, noting that, prior to receiving chelation therapy, his patients signed a consent form explaining the possible benefits and side effects of the treatment (very similar to that later approved in 4 CSR 150-2.165), and stating that the treatment was not approved by the FDA, the AMA, or other recognized medical organizations for the treatment of vascular disease. In addition to chelation therapy, Dr. McDo-nagh encouraged patients to follow a diet and exercise plan, and did not discourage patients from seeing other physicians, including specialists.
The AHC held a hearing in November 1997. The Board introduced expert testimony that the use of chelation therapy to treat vascular disease is not generally accepted in the field of treatment of vascular disease and does not meet the standard of care for treatment of vascular disease. Dr. McDonagh offered expert testimony that supported his off-label use of chelation therapy to treat vascular disease. The Board objected. The AHC heard all of the evidence without ruling on its admissibility, as permitted by section 536.070(7), which provides that evidence subject to an objection “nevertheless be heard and preserved in the record.” The AHC ultimately ruled that the testimony was admissible, found no evidence of harm from chelation therapy, rejected all thirteen counts, and found no cause to discipline Dr. McDo-nagh’s medical license.
The circuit court affirmed the AHC’s decision. The Board appealed. Following opinion by the Missouri Court of Appeals, Western District, this Court granted *152transfer to address the standards for admission of expert testimony in civil and administrative cases. Mo. Const, art. V, secs. 10, 18.
II. STANDARD OF REVIEW
On appeal, this Court reviews the AHC’s decision, rather than that of the trial court, to determine whether the agency action:
(1) Is in violation of constitutional provisions;
(2) Is in excess of the statutory authority or jurisdiction of the agency;
(3) Is unsupported by competent and substantial evidence upon the whole record;
(4) Is, for any other reason, unauthorized by law;
(5) Is made upon unlawful procedure or without a fair trial;
(6) Is arbitrary, capricious or unreasonable;
(7) Involves an abuse of discretion.
Sec. 536.140.2; Sec. 621.145; Psychcare Mgmt., Inc. v. Dep’t of Soc. Servs., Div. of Med. Servs., 980 S.W.2d 311, 312 (Mo. banc 1998). Here, the Board argues that the decision was not “supported by competent and substantial evidence upon the whole record” and that “it was arbitrary, capricious, unreasonable or an abuse of discretion.” Ross v. Robb, 662 S.W.2d 257, 259 (Mo. banc 1983). A reviewing court will refrain from substituting its judgment for that of the AHC on factual matters. Psychcare Mgmt., Inc., 980 S.W.2d at 312. Questions of law are matters for the independent judgment of this Court. Gammaitoni v. Dir. of Revenue, 786 S.W.2d 126, 128 (Mo. banc 1990).
III. STANDARD FOR ADMISSIBILITY OF EXPERT TESTIMONY
A. Section 4.90.065 Provides the Standard for Admission of Expert Testimony in Civil Actions.
The Board suggests the standard for admission of expert testimony is that set out in Frye and previously applied by this Court. See Alsbach v. Bader, 700 S.W.2d 823, 828-30 (Mo. banc 1985). Frye states that, for expert testimony to be admissible, “the thing from which the [expert’s] deduction is made must be sufficiently established to have gained general acceptance in the particular field in which it belongs.” 239 F. at 1014.
Dr. McDonagh counters that, although this Court once adopted the Frye test, the relevant standard for admission of expert testimony is now either that set forth by the. Supreme Court of the United States in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993), for application in the federal courts, or that set out in section 490.065. The latter statute says:
1. In any civil action, if scientific, technical or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education may testify thereto in the form of an opinion or otherwise.
2. Testimony by such an expert witness in the form of an opinion or inference otherwise admissible is not objectionable because it embraces an ultimate issue to be decided by the trier of fact.
3. The facts or data in a particular case upon which an expert bases an opinion or inference may be those perceived by or made known to him at or before the hearing and must be of a type reasonably relied upon by experts in the field *153in forming opinions or inferences upon the subject and must be otherwise reasonably reliable.
4. If a reasonable foundation is laid, an expert may testify in terms of opinion or inference and give the reasons therefor without the use of hypothetical questions, unless the court believes the use of a hypothetical question will make the expert’s opinion more understandable or of greater assistance to the jury due to the particular facts of the case.
Although section 490.065 on its face states that it applies in civil actions and sets out the relevant standard for admission of expert testimony in such actions, various decisions of Missouri’s court of appeals since section 490.065 was enacted in 1989 have expressed confusion as to whether it is the statute, Frye, or Daubert that supplies the relevant standard for admission of expert testimony.9
Any such confusion should have been resolved by this Court’s 1997 decision in Lasky holding that section 490.065 provides the applicable standard “in evaluating the admission of expert testimony” in civil cases. 936 S.W.2d at 802. While Lasky did not further expressly state that to the extent that prior civil cases applied a different rule they should no longer be followed, such a holding was implicit in Lasky ⅛ direction that “on remand the trial court shall be guided by section 490.065, RSMo, in evaluating the admission of expert testimony.” Id. at 801.
To clarify, however, this Court expressly holds that to the extent that cases since Lasky have suggested that the standard of admissibility of expert testimony in civil cases is that set forth in Frye or some other standard, they are no longer to be followed. The relevant standard is that set out in section 490.065.
B. Section 190.065’s Applicability to Contested Administrative Proceedings.
The Board alternatively argues that because the first four words of section 490.065 are “in any civil action,” the standard for admission of expert testimony it sets out could have no application to ad*154ministrative actions such as this one. In support, the Board cites cases that have noted that administrative actions generally are tried in accordance with various rules of administrative procedure rather than in accordance with Missouri’s rules of civil procedure, except to the extent that the latter have been adopted by statute for use in administrative cases. See, e.g., Wheeler v. Bd. of Police Comm’rs of Kansas City, 918 S.W.2d 800, 803 (Mo.App. W.D.1996); Dillon v. Dir. of Revenue, 777 S.W.2d 326, 329 (Mo.App. W.D.1989). The admission of expert testimony is not determined by rules of civil or administrative procedure, however, but by principles governing the admissibility of evidence. The relevant ev-identiary principles are not set out in any set of rules, but rather have been developed by common law and by statute.10 These principles govern the admission of evidence in civil and criminal cases.
Cases brought before administrative agencies generally are less formal and structured than are civil proceedings in the circuit courts. That does not mean that evidentiary rules developed in civil cases have no application to administrative actions, however. To the contrary, the legislature has specifically directed that many evidentiary principles developed in civil actions be applied in administrative ones, including those regarding privilege, judi-eial notice, admission of writings and documents, depositions, and so forth.11
This Court has further held that other, basic principles of evidence also apply in administrative proceedings. Thus, in Missouri Church of Scientology v. State Tax Commission, 560 S.W.2d 837, 839 (Mo. banc 1977), this Court stated, “[ajlthough technical rules of evidence are not controlling in administrative hearings, fundamental rules of evidence are applicable.” The principle set out in Missouri Church of Scientology reiterates a principle this Court recognized at least as long ago as State ex rel. De Weese v. Morris, 359 Mo. 194, 221 S.W.2d 206, 209 (1949), in which this Court stated, “[tjhe fact that technical rules of evidence do not control has been considered to permit of leading questions and other informalities but not to abrogate the fundamental rules of evidence.” See also State ex rel. Bond v. Simmons, 299 S.W.2d 540, 545 (Mo.App.1957) (accord).
The approach set out in these cases applies here. While contested administrative proceedings are not required to follow the “technical rules of evidence,” the “fundamental rules of evidence” applicable to civil cases also are applicable in such administrative hearings. See Mo. Church of Scientology, 560 S.W.2d at 839; De Weese, 221 S.W.2d at 209. The standards for admission of expert testimony constitute *155such a fundamental rule of evidence. The standards set out in section 490.065 therefore guide the admission of expert testimony in contested case administrative proceedings such as this one.
C. Comparison of Section 4,90.065 with FRE 702, FRE 70S, and Daubert.
The parties and the AHC seem to assume that section 490.065 and FRE 702 and FRE 703, as interpreted in Daubert, are effectively identical, and that the standard set out in section 490.065 mirrors that Daubert adopted for use in the federal courts.
Daubert held “[t]hat the Frye test was displaced by the [Federal] Rules of Evidence.” 509 U.S. at 589, 113 S.Ct. 2786. It found that FRE 702 provides a more “flexible” standard for admissibility focused on “the scientific validity and thus the evidentiary relevance and reliability— of the principles that underlie a proposed submission.” Id. at 594-95, 113 S.Ct. 2786 (noting that “[t]he focus ... must be solely on principles and methodology, not on the conclusions that they generate”).
Daubert set out a non-exclusive list of factors for consideration in determining whether the evidence in question meets the flexible standard, including: (1) “whether [the theory or technique] can be (and has been) tested”; (2) “whether the theory or technique has been subjected to peer review and publication”; (3) “the known or potential rate of error”; and (4) “ ‘general acceptance.’ ” Id. at 593-94,113 S.Ct. 2786.
The Supreme Court summarized its holding by emphasizing the difference between Daubert and the Frye test that the federal courts had previously employed, stating: “ ‘General acceptance’ is not a necessary precondition to the admissibility of scientific evidence under the Federal Rules of Evidence....” Id. at 597, 113 S.Ct. 2786.
Few cases have interpreted section 490.065. To the extent that section 490.065 mirrors FRE 702 and FRE 703, as interpreted and applied in Daubert and its progeny, the cases interpreting those federal rules provide relevant and useful guidance in interpreting and applying section 490.065. See Giddens v. Kansas City S. Ry. Co., 29 S.W.3d 813, 820 (Mo. banc 2000) (“The construction given by the federal courts to their rules does not control the interpretation of our state rules, even if the rules themselves are nearly identical. However, the experiences of those courts in applying rules similar to our own are illustrative”). To the extent that the two approaches differ, however, the standard set out in section 490.065 must govern.
The standard set out in section 490.065 is very similar to that initially adopted by the federal courts in Daubert and set out in FRE 702. Indeed, at the time Daubert was decided, FRE 702 was identical to section 490.065.1, stating, “If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise,” except that section 490.065.1 added a preliminary phrase “[i]n any civil action.”12
*156While the parties presume that section 490.065.3 is also effectively identical to FRE 703, review of the two rules reveals important differences. Section 490.065.3 begins by stating, “The facts or data in a particular case upon which an expert bases an opinion or inference may be those perceived by or made known to him at or before the hearing.” The first sentence of FRE 703 is identical except for minor stylistic variations.
But, section 490.065.3 goes on to require that the facts or data on which an expert bases an opinion or inference “must be of a type reasonably relied upon by experts in the field in forming opinions or inferences upon the subject” and that these facts and data “must be otherwise reasonably reliable.” Sec. 490.065.3. Thus, section J/.90.065.S expressly requires a showing that the facts and data are of a type reasonably relied on by experts in the field in forming opinions or inferences upon the subject of the expert’s testimony. The court must also independently assess their reliability. Id.
By contrast, under FRE 703 whether the facts or data relied upon are “of a type reasonably relied upon by experts in the particular field in forming opinions or inferences upon the subject” is relevant only to determine whether the facts or data must be otherwise admissible in evidence. For this reason, unlike in Missouri, Daubert held that in the federal courts an expert need not necessarily identify the relevant scientific community, or field, in which the data and facts are accepted. Daubert, 509 U.S. at 594, 113 S.Ct. 2786.
IV. APPLICATION OF SECTION 4.90.065 TO DR. McDONAGH’S EXPERTS
The differences between section 490.065 and FRE 703 as interpreted in Daubert take on great importance here because a key area of disagreement of the parties concerns identification of the relevant scientific field by which Dr. McDonagh’s practices are to be judged. This is essential because the statute requires that to be admissible expert opinion must be based on facts or data of a type reasonably relied upon by “experts in the field.”
A. Identification of Relevant Field of Experts.
Dr. McDonagh argued, and the AHC appeared to determine, that the relevant “field” for purposes of this inquiry is the universe of medical practitioners who utilize chelation therapy. And, as the record shows that Dr. McDonagh followed the protocol for use of chelation therapy approved by the approximately 1,000 doctors who are organized into ACAM, it concluded that his experts’ testimony as to whether his treatments were appropriate was admissible. But, to limit the relevant “field” to only those doctors who have already expressed their view that the therapy in question is appropriate would make the inquiry into acceptance by experts in the field pointless, for, by definition, only those who had accepted the therapy would be asked for their opinion.
The relevant field must be determined not by the approach a particular doctor chooses to take, but by the standards in the field in which the doctor has chosen to practice. As relevant here, Dr. McDonagh chose to treat patients with vascular disease. The Board’s claim is that Dr. McDonagh engaged in repeated negligence or misrepresentation and was otherwise in violation of the relevant statutes in his provision of chelation therapy for these patients. Therefore, the relevant field is doctors treating persons with vascular disease. The facts or data on which Dr. McDonagh’s experts rely, therefore, *157must be those perceived by them at trial or must be of a type reasonably relied on by doctors treating vascular disease.13
By so stating, this Court is not in effect readopting the Frye standard under another name. Nothing in section 490.065 suggests that the conclusions reached in reliance on these facts and data must be in conformity with the general medical consensus or must be generally accepted. As under Daubert and cases applying it, such acceptance is but one factor of the relevant inquiry. Section 490.065.3 simply requires the court to consider whether the facts and data used by the expert are of a type reasonably relied on by experts in that field or if the methodology is otherwise reasonably reliable. If not, then the testimony does not meet the statutory standard and is inadmissible.
B. Necessity of Controlled Studies.
The Board argues that, even if Daubert — for which section 490.06514 is interpolated — provides the standards for admission of expert testimony, the testimony of Dr. McDonagh’s experts should have been excluded because controlled studies supporting use of chelation therapy to treat vascular disease do not exist.
Nothing in section 490.065 expressly requires such studies. The Board cites to no case decided under section 490.065 requiring that an expert opinion be supported by controlled studies in order to be admissible. To the contrary, section 490.065.3 states that an expert’s opinion is admissible if the facts or data on which the opinion is based are “of a type reasonably relied upon by experts in the field in forming opinions or inferences upon the subject” and are “otherwise reasonably reliable.” Controlled studies are a form of data. Therefore, the admissibility of an expert’s opinion depends not on some immutable, external standard — such as the presence of controlled studies — but on whether experts in the particular field can reasonably rely on other types of data in forming their opinions, or whether in that field controlled studies are required. But, the AMA has suggested that controlled studies must be done before chelation therapy will be generally recognized as effective. See AMA, AMA Policy Compendium H-175.994 (1994) supra. Of course, section 490.065.3 also imposes an independent duty on the court to determine whether the facts and data relied on are otherwise reasonably rehable. The lack of controlled studies presumably would be relevant, but not necessarily dispositive, in making this determination. This is consistent with the approach under Daubert and FRE 703. Daubert says that whether the theory is or can be tested as a controlled study would do — is merely one factor, albeit an important one, in determining its admissibility. 509 U.S. at 593-94, 113 S.Ct. 2786.
As applied here, it was up to the AHC to consider Dr. McDonagh’s experts’ testimony, along with the other evidence offered on the issue, and determine whether experts in the field could reasonably rely on the data those experts relied on in reach*158ing their conclusions about the use of che-lation therapy. Because of the confusion in the cases in regard to the standard for admission of expert testimony, the AHC did not apply these standards in evaluating the expert testimony offered. On remand, the AHC may permit the parties to supplement the record with additional expert testimony addressing the issues relevant under the statute.
V. REMAINING ISSUES ON APPEAL
A. Necessity of Expert Testimony on Standard of Care for Repeated Negligence Under Section 381.100.2(5).
The Board alternatively argues that, even were the testimony of Dr. McDonagh’s experts otherwise admissible under the relevant evidentiary standard, it was insufficient to counter the Board’s allegations in various counts, and through expert and other evidence, that Dr. McDo-nagh’s use of chelation therapy constituted “repeated negligence” as that term is used in section 334.100.2(5).15 That section defines “repeated negligence” as “the failure, on more than one occasion, to use that degree of skill and learning ordinarily used under the same or similar circumstances by the member[s] of the applicant’s or licensee’s profession.” Sec. 334.100.2(5).
The Board submits that, in order to counter the Board’s experts, Dr. McDo-nagh’s experts needed to testify as to whether he used the degree of skill and learning ordinarily used by members of his profession. But, while his experts testified that his treatment of his patients met “the standard of care,” they never identified that standard of care. The Board argues that the standard of care he met must be the standard of care generally accepted in the profession, and this means that Dr. McDonagh is negligent if he treats his patients in a way other than the treatment generally offered by doctors in the field. And, given Dr. McDonagh’s experts’ admission that mainstream doctors generally do not use chelation therapy to treat vascular disease, the Board suggests, Dr. McDonagh’s experts cannot have used the correct standard of care in giving their opinion that his treatment met the required standard.
Dr. McDonagh admits that his experts did not state by what standard of care they were evaluating his treatment of his patients, but argues, to the extent testimony as to the standard of care was necessary,16 the standard is that used by *159doctors who apply chelation therapy. In effect, he argues that, because he used the protocol approved by ACAM, he could not be found to be negligent and necessarily met the requisite standard of care.
Neither party’s argument is correct. The relevant standard of care is neither a reformulation of the Frye general acceptance test, nor blind acceptance of the views of a subgroup of treaters. The relevant standard of care for discipline for repeated negligence is necessarily that set out in the statute addressing that conduct, section 334.100.2(5). That standard, similar to Missouri’s standard for proof of negligence in civil cases,17 requires a showing whether the doctor showed the “skill and learning ordinarily used under the same or similar circumstances by the member[s] of [the doctor’s] profession.” Sec. 334.100.2(5) (emphasis added). As the issue here is the treatment of persons with vascular disease, the appropriate standard of care is that used by doctors treating persons with vascular disease.
Application of this standard does not merely require a determination of what treatment is most popular. Were that the only determinant of skill and learning, any physician who used a medicine for off-label purposes, or who pursued unconventional courses of treatment, could be found to have engaged in repeated negligence and be subject to discipline. This would not be consistent with section 490.065.
Rather the statute requires only what it says — that Dr. McDonagh use that degree of skill and learning used by members of the profession in similar circumstances. By analogy, one doctor may use medicine to treat heart problems while another might chose to perform a by-pass and a third to perform angioplasty, yet all three may be applying the requisite degree of skill and learning. That they came to differing conclusions by applying that skill and learning does not make one negligent and one non-negligent.
So too, here, if Dr. McDonagh’s treatment, including his use of a diet and exercise regimen, and the lack of evidence of harm from his approach, demonstrates the application of the degree of skill and learning ordinarily used by members of his profession, then it is not a basis for discipline under the statute, even if other doctors would apply these facts to reach a different result.
Because, in concluding that Dr. McDo-nagh did not violate section 334.100.2(5), the AHC relied on Dr. McDonagh’s experts’ testimony and because this testimony failed to establish whether the experts were using the legal standard of care for “repeated negligence” set out in section 334.100.2(5), this Court must reverse and remand. The circuit court should remand to the AHC for reconsideration under section 490.065 and in light of the standard of care contained in section 334.100.2(5).
B. Record Keeping, Testing, and Misrepresentation Issues.
The parties dispute the AHC’s findings and conclusions on the allegations that Dr. McDonagh failed to keep and maintain adequate records. These allegations were made as part of Counts II, III, IV, V, X, and XII, rather than set out in an independent count, and the Board presented expert testimony on Dr. McDonagh’s record-keeping practices in regard to the *160standard of care. While the AHC made an independent finding that “no Missouri law or regulation sets forth standards or recommendations,”18 it failed to consider the evidence as a component of the repeated negligence counts in which the allegations of inadequate record keeping arose. It should do so on remand.
The Board and Dr. McDonagh also dispute the AHC’s findings regarding the Board’s allegations of misrepresentation, and his alleged repeated ordering of inappropriate and unnecessary testing of patients. These issues should be remanded to the AHC for reconsideration in light of this opinion.19
VI. CONCLUSION
Because the expert testimony upon which the AHC relied failed to furnish the appropriate legal standard of care, the circuit court’s judgment is reversed, and the case is remanded. On remand, the circuit court is directed to remand to the AHC on all counts for further review in light of section 490.065 and in light of the standard of care set out in section 334.100.2(5) and this opinion.

In 1999, the Federal Trade Commission and ACAM entered into a consent agreement under which ACAM agreed not to make any representations regarding EDTA chelation therapy's effectiveness as a treatment for atherosclerosis. In re Am. Coll, for Advancement in Med., No. C-3882 (Fed. Trade Comm’n June 22, 1999) at http:// www.ftc.gov/os/1999/07 /9623147c3881acam.do.htm. See also American College for Advancement in Medicine, 64 Fed.Reg. 12,338 (Fed. Trade Comm’n Mar. 12, 1999) (extension of public comment period on consent agreement).
.The first of these studies was the Guldager study, published in 1992, and the second was the van Rij study, published in 1994. These studies tested the efficacy of EDTA chelation therapy in treating intermittent claudication, which is "[a]n aching, crampy, tired, and sometimes burning pain in the legs that comes and goes ... due to poor circulation of blood in the arteries of the legs.” Medici-neNet.com, Medical Diet., at http://www.medicinenet.com/scrip1/ main/art.asp?ArticleKey=9218 & pf=3 & track=qpadict (last visited Oct. 30, 2003).
. The Board alleged violations of numerous versions of the statute from 1976 through at least 1994.
. Count VI, which alleged improper delegation of professional responsibilities to unqualified personnel, was not raised on appeal.
. See, e.g., McReynolds v. Mindrup, 108 5.W.3d 662, 665-66 & n. 2 (Mo.App. W.D. 2002) ("whether [section] 490.065 supersedes the Frye doctrine ... has not yet been decided by our Supreme Court” and "no Missouri case has yet decided what, if any, impact adoption of [section] 490.065 has on the application of the Frye 'general acceptance' rule, much less whether it compels application of the Daubert standard,” citing section 490.065 for the admissibility of expert testimony, and stating that Frye is the proper standard for analyzing the admissibility of expert testimony related to scientific techniques); Keyser v. Keyser, 81 S.W.3d 164, 169 (Mo.App. W.D. 2002) (citing section 490.065.3 as the standard for the admissibility of expert testimony without reference to either Frye or Daubert); Long v. Mo. Delta Med. Ctr., 33 S.W.3d 629, 642-43 (Mo.App. S.D.2000) (noting that section 490.065’s "adoption may create the question if Missouri courts should continue to apply the Frye standard to the admissibility of expert testimony, or if Daubert would be more appropriate,” then applying Frye to the admissibility of expert testimony regarding scientific techniques, and holding that section 490.065 applies to the admissibility of expert testimony regarding non-scientific evidence); M.C. v. Yeargin, 11 S.W.3d 604, 619 (Mo.App. E.D.1999) (noting that "[t]he Missouri Supreme Court continues to apply the Frye test to the admissibility of expert testimony in criminal cases and in civil cases,” and finding that “the trial court abused its discretion in admitting [the expert’s] testimony because the court did not find that he based it on scientific principles generally accepted in the relevant scientific community or within the boundaries of Section 490.065”); Whitman’s Candies, Inc. v. Pet, Inc., 974 S.W.2d 519, 528 (Mo.App. W.D.1998) ("[b]ecause the expert testimony at issue in the case at bar satisfies the requirements of both Frye and Daubert, this court need not determine whether [section] 490.065 supersedes the Frye test in Missouri” (emphasis in original)).
. Indeed, although Missouri’s Constitution leaves it to this Court to develop rules of procedure, it specifically prohibits the Supreme Court from creating rules of evidence. Mo. Const, art. V, sec. 5. See State v. Williams, 729. S.W.2d 197, 201 (Mo. banc 1987) ("[T]he legislature has plenary power to prescribe or alter the rules of evidence....").
. See, e.g., secs. 536.070(6) ("Agencies shall take official notice of all matters of which the courts take judicial notice.”); 536.070(8) (“The rules of privilege shall be effective to the same extent that they-are now or may hereafter be in civil actions." (emphasis added)); 536.070(9) (As to "[c]opies of writings, documents and records,” “the agency may, nevertheless, if it believes the interests of justice so require, sustain any objection to such evidence which would he sustained were the proffered evidence offered in a civil action in the circuit court. ...” (emphasis added)); 536.073.1 ("[A]ny party may take and use depositions in the same manner, upon and under the same conditions, and upon the same notice, as is or may hereafter be provided for with respect to the taking and using of depositions in civil actions in the circuit court. ...” (emphasis added)).
. The effect of the addition of the phrase "in any civil action” is discussed supra. In 2000, language was added to the end of FRE 702 setting out in greater detail how the trial court, in its role as gatekeeper, should review the expert’s testimony, stating that the court should find the testimony admissible "if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.”
. Cf. Yantzi v. Norton, 927 S.W.2d 427 (Mo.App. W.D.1996) (negligence of professional engineer engaging in foundation repair was to be judged by standards of those with expertise in foundation repair, not merely by those who are professional engineers).
. Dr. McDonagh objects that the Board has not preserved its objections to admission of his experts’ testimony under section 490.065, and instead merely argued the testimony was inadmissible under Frye or Daubert. But, because the parties and AHC used the term "Daubert ” to refer generally to any non-Frye approach to expert testimony, this Court finds it appropriate to reach the merits of the Board’s arguments in this regard.
. The Court notes that the term "repeated negligence” was not added to the statute until 1987. Therefore, although much of the conduct discussed at the hearing and that forms the basis of the Board's action occurred prior to 1987, the "repeated negligence” aspect of the Board’s assertions of misconduct against Dr. McDonagh can be based only on his conduct after that provision was added to the statute.
. Dr. McDonagh argues that expert testimony on the standard of care was not necessary. This Court disagrees. Because this case deals with complex issues as to the appropriate medical care for patients with vascular disease, a matter not within lay competence, expert testimony was necessary to determine what standard of care was required of Dr. McDonagh and whether he met that standard of care. See, e.g., Swope v. Printz, 468 S.W.2d 34, 40 (Mo.1971) (in medical malpractice cases, experts must incorporate the legal standard of care into their testimony to show that it is not "based upon [the expert's] own undisclosed subjective conception of acceptable medical standards” rather than the required, objective legal standard of care); Ladish v. Gordon, 879 S.W.2d 623, 634-35 (Mo.App. W.D.1994) ("[i]t is not necessary that the legal standard be recited in ritualistic fashion, but generally it must appear somewhere in the context of the expert’s testimony that the proper objective legal standard is the standard being employed by this expert”); Dine v. Williams, 830 S.W.2d 453, 456 (Mo.App. W.D.1992) (accord).
. See, e.g., Silberstein v. Berwald, 460 S.W.2d 707, 709 (Mo.1970) (“The defendant was required to use and exercise that degree of skill and proficiency which is commonly experienced by the ordinary, skillful, careful and prudent physician and surgeon engaged in the practice of medicine”); Hart v. Steele, 416 S.W.2d 927, 931 (Mo.1967) (accord); Williams v. Chamberlain, 316 S.W.2d 505, 510 (Mo.1958) (accord).
. In 2002, the Missouri General Assembly passed section 334.097, governing the maintenance of medical records. Sec. 334.097, RSMo Supp.2002.
. Because of the resolution of the other issues addressed above, it is unnecessary for the Court to address Dr. McDonagh’s argument that adoption of the Board's position on chelation therapy would constitute an unreasonable restraint on his right and the right of his patients to choose alternative medicine treatment modalities.
