OPINION
K.K. HALL, Circuit Judge:The American National Red Cross Blood Services, Carolina Lowcountry Region (“Red Cross”) brings this interlocutory appeal pursuant to 28 U.S.C. § 1292(b) to complain about the district court’s order granting plaintiff Cynthia Watson’s motion to compel certain discovery concerning a blood donor. We affirm.
I.
On February 10, 1985, Cynthia Watson gave birth to premature twins in Charleston, South Carolina. Trevor, one of the babies, received a number of blood transfusions through April, 1985. In 1986, he tested positive for HIV, and he later developed AIDS. He died in 1988.
Cynthia Watson was appointed adminis-tratrix of Trevor’s estate. In December, 1988, she filed this wrongful death action against the Red Cross and the hospital at which Trevor received the blood transfusions following his birth.1 The hospital *484used blood supplied by the Red Cross, and the Red Cross was able to determine that only one of the six donors whose blood was used in these transfusions might have been HIV-positive when the blood was donated. Watson sought to discover from this unidentified “implicated donor” information about his background and about the donation process itself. One theory of liability is that the screening process to which the implicated donor was subjected was inadequately and negligently carried out by the Red Cross employees at the donor station.
Extensive discovery has already taken place in this case. Both of the nurses on duty at the donation center on the day in question have been deposed.2 Not surprisingly, neither was able to remember the implicated donor, whom they screened some five years earlier. The Red Cross has also provided Watson with many non-identifying pieces of information about the donor, including a redacted copy of the screening questionnaire completed by him on February 27, 1985. Watson persisted, however, in her request for the identity of the donor or, alternatively, for the opportunity to question him through a court-appointed intermediary. The Red Cross moved for a protective order, and the matter was referred to the magistrate judge.
The magistrate recognized that some discovery from the donor is crucial to Watson’s case against Red Cross, at least insofar as the claims of negligence rest on how this particular donor was screened on the day in question. The magistrate dismissed as factually unfounded the Red Cross’s claims that the invasion of the donor’s privacy would seriously jeopardize the nation’s blood supply. It was recommended that the donor’s identity be divulged to the court and that a lawyer be appointed to represent the donor’s interests. The lawyer’s name would also remain confidential, known only to the court. Watson would be permitted to file proposed interrogatories3 to which the Red Cross could object. The approved questions would then be given to the donor’s lawyer to forward to his client, and the answers (with the donor’s verification redacted) would then be delivered to the parties.
The Red Cross filed objections to the report, and argument was held before the district court. The district court accepted the recommendations, and in February, 1991, a set of interrogatories was approved. Essentially, these interrogatories delve into the donor’s blood-donation history, with particular emphasis on the February 27 donation. Some of the interrogatories inquire into some limited aspects of the donor’s personal history. The district court granted the Red Cross’s motion for a stay and certification for permission to take an interlocutory appeal pursuant to 28 U.S.C. § 1292(b). A panel of this court granted leave to file the appeal.
II.
The issues before us are well-defined, and the arguments for each side have been honed before a score of courts and analyzed in numerous law review articles. Yet the courts have been unable to reach a consensus on any of the major issues involved in such actions. As formulated by the district court, the precise “controlling question of law” certified for our review is “whether direct discovery from an anonymous volunteer blood donor should be prohibited under Federal Rules of Civil Procedure 26(c), and/or the Constitutions of the *485United States and the State of South Carolina.” Watson v. Medical University of South Carolina, C/A 88-2844-18 (D.S.C. Feb. 25,1991). Although couched in broad, general terms, the issues before us may only be meaningfully analyzed by reference to the particular discovery scheme embodied in the protective order.4
A.
We begin by setting forth the pertinent legal standards under which the protective order should be reviewed. First, the district court is subject to the broad admonitions of Fed.R.Civ.P. 26(b) in fashioning discovery orders. All non-privileged information that is either admissible at trial or that “appears reasonably calculated to lead to the discovery of admissible evidence” should be discoverable. Fed.R.Civ.P. 26(b)(1). However, protection may be granted to any person from whom discovery is sought to prevent “annoyance, embarrassment, oppression, or undue burden or expense.” Fed.R.Civ.P. 26(c). On appeal, Red Cross asserts that the only standard of review should be de novo for its “claims of legal errors.” What are put forth as “legal errors,” however, are more accurately characterized as matters involving either fact-finding or an exercise of discretion by the district court. The Red Cross’s attempt to paint this case in stark, urgent colors is unsuccessful.
We will follow the established standards of review.
If the claim is of error in underlying factfindings which infected the ultimate decision, review must proceed under the clearly erroneous standard; if of error of law infecting the ultimate decision, under the de novo review standard. Only if the claim of error goes exclusively to the impropriety of an ultimate exercise of available discretion is review solely under the abuse of discretion standard.
United Food & Commercial Workers v. Marval Poultry Co., 876 F.2d 346, 351 (4th Cir.1989). The threshold task throughout is to properly categorize the various aspects of the lower court’s order as findings of fact, conclusions of law, mixed fact-law rulings, or exercises of discretion.
B.
The Red Cross contends that Watson’s interest in the discovery approved by the court is outweighed by two countervailing interests: the nation’s interest in a safe and adequate blood supply and the implicated donor’s privacy interests. We turn first to how the proposed discovery purported to pose a danger to the adequacy of the nation’s blood supply.
The Red Cross’s argument is that allowing plaintiffs to “enmesh” blood donors in tort actions of this kind will inevitably result in fewer persons willing to donate blood. As more cases of this type are publicized, potential donors will decide that the risk of becoming involved in litigation, with the possibility that their personal lives will be made public, outweighs the benefits of donating their blood. Although the Red Cross currently promises that the donors’ records will remain confidential, such promises may not be able to be made if donor discovery is permitted in a sufficiently large number of cases like the instant one. Fewer donors, of course, means less blood.
Notwithstanding the Red Cross’s repeated assertions to the contrary, however, the district court did not rule that Watson’s interest in the contested discovery outweighed the public interest in maintaining an adequate supply of healthy volunteer blood. Rather, the court ruled that “there is not one shred of tangible evidence in the nature of hard statistical data to substantiate an otherwise speculative claim that the blood supply will be jeopardized.” Watson v. Medical University of South Carolina, C/A No. 88-2844-18 (D.S.C. Feb. 7, 1991) (order). On appeal, the Red Cross attempts to deflect the impact of this ruling by pointing to a number of eases in which courts have denied discovery requests from similarly implicated donors. See, e.g., Rasmussen v. South Florida Blood Service, 500 So.2d 533, 538 (Fla.1987) (“[Tjhere is *486little doubt that the prospect of inquiry into one’s private life and potential association with AIDS will deter blood donation... Coleman v. American Red Cross, 130 F.R.D. 360, 362 (E.D.Mich.1990) (“There is no question that court ordered disclosure will have a serious impact on volunteer blood donations.”). In none of these cases, however, is there any mention of any statistical or empirical underpinning for the stated concerns about the effect on the blood supply.
Of course, the Red Cross offered the opinion testimony of an expert in the field. Again, however, Dr. Cannon’s opinions are couched in conclusory terms. His proffered syllogism goes like this: donors desire anonymity and confidentiality; “donors would be much less likely to donate blood if they knew there was a risk, however small, that their identities, medical histories, and test result might be revealed to the recipients of the blood;” therefore, blood supplies will drop to dangerously low levels. Aside from the fact that the identity of the implicated donor in this case is not to be revealed to Watson under the protective order, the expert opinion is grounded upon nothing more than a seemingly logical theory of human behavior. Moreover, Dr. Cannon’s opinion is directly countered by Watson’s expert, Dr. Eisenmann, president of the Association for Improvement of Volunteer Blood Donation.
In an affidavit filed with the district court, Dr. Eisenmann stated that “granting the plaintiffs’ request for access to the implicated donor in the above captioned matter is extremely unlikely to have any measurable effect on the availability of blood for transfusion, and certainly not the major impact that Dr. Cannon supposes.” Dr. Eisenmann concluded by stating that any effect on donors would be a salutary one because the safety of the blood supply might well be enhanced if potential donors at high risk for HIV were discouraged from donating out of fear of enmeshing themselves in litigation.
In sum, the opinions of courts and experts go both ways.5 The district court’s ruling rejected the factual predicate upon which the Red Cross’s balancing test was premised, i.e., that access to implicated donors would lead to a dangerous depletion of the blood supply because many potential donors would decline to donate out of fear of becoming involved in similar litigation.6 We cannot say that this finding of fact is clearly erroneous. Having so decided, we need not balance the interest of plaintiff and the nation.7
C.
The Red Cross makes a related argument about the potential effect on the blood supply. Donor screening depends in large part on receiving an accurate health history from each donor in order that high-risk persons be excluded. The Red Cross raises the specter of donors lying about their health histories in order that they be permitted to donate blood. Lying, of course, will neither insulate them from litigation nor will it bode well for them should their donations be implicated in the transmission of disease. It strikes us that a person willing to spend an hour or more so that a needle can be placed in his or her vein and a pint of blood extracted is not the sort of person who would lie for the privilege of doing so.8 The potential for involvement in *487litigation will not be lessened by giving false answers during screening; if anything, such a lack of candor may well exonerate the donation center, while at the same time shifting the focus of liability to the donor where none might otherwise have existed. In short, the asserted fear is illogical.
III.
The Red Cross also assails the district court’s refusal to hold that the implicated donor’s privacy interests should prevent even a limited disclosure of his identity and discovery. The district court believed that the protective order and the questions to be propounded did not implicate the donor’s constitutionally protected privacy rights; alternatively, even if such rights are implicated, these rights are outweighed by the competing interest of the plaintiff in obtaining the information. We believe both of these holdings are correct.
A.
We accept the contention that the Red Cross has standing to raise the donor’s constitutional rights. Doe v. American Red Cross Blood Services, 125 F.R.D. 646, 650 n. 1 (D.S.C.1989). It is difficult, however, to discern the precise nature of the right that the Red Cross is seeking to protect. The Red Cross appears to identify two separate aspects of the purported right that would be violated if the discovery were to proceed as ordered. First, the possibility of inadvertent disclosure of the donor’s identity might cause grievous harm to the donor. Second, the questions approved by the district court would embarrass and harass the implicated donor. We fail to see how the approved discovery affects either of these aspects of privacy in a manner prohibited by the federal or South Carolina constitutions.
The danger of public disclosure is a red herring. The Red Cross cites a slew of cases for the proposition that there is a protectable right to privacy in one’s medical records. See, e.g., United States v. Westinghouse Elec. Corp., 638 F.2d 570, 577 (3rd Cir.1980) (“There can be no question that an employee’s medical records, which may contain intimate facts of a personal nature, are well within the ambit of personal materials entitled to privacy protection.”). The stigma attached to AIDS lends even more weight to the argument that the medical records of its victims should receive scrupulously confidential treatment. See Woods v. White, 689 F.Supp. 874 (W.D.Wis.1988), aff'd mem., 899 F.2d 17 (7th Cir.1990) (disclosure by state health employees to non-medical personnel that plaintiff-inmate had tested positive for AIDS held to state a claim for violation of inmate’s constitutional right to privacy). The Red Cross’s arguments fall short, however, when they are examined in the specific context of this case.
The Supreme Court gave short shrift to a similar argument in Whalen v. Roe, 429 U.S. 589, 97 S.Ct. 869, 51 L.Ed.2d 64 (1977). A state statute required that the names and addresses of all persons who received prescriptions for certain drugs that were also sold illegally be recorded in a centralized computer file. Physicians and patients argued that the statute violated their constitutional rights of privacy because, among other reasons, there existed a possibility that the names of patients obtaining such prescriptions might be disclosed publicly. The Court found no evidence that the collection and storage of the information would be improperly administered by either the state or, in the event the stored data were to be used as evidence in a judicial proceeding, by the courts. Accordingly, the potential for public disclosure was held to be an insufficient basis for finding a violation of the rights of privacy. Id. at 598-602, 97 S.Ct. at 875-878.
The possibility of public disclosure is even more remote in the case before us. The implicated donor’s identity, already known to the Red Cross, would be revealed to only the court and to the lawyer appointed by the court. The revelation to the court, moreover, is to be made directly to the judge by the Red Cross, to be hand delivered in an envelope marked “Personal and Confidential.” All answers are to be maintained in a sealed envelope marked *488“Confidential,” and the answers provided by the donor must have the signature redacted prior to filing. We cannot conceive of a better system to maintain the confidentiality of the donor’s identity. The potential for disclosure does not rise to the level of a violation of the privacy rights of the donor.9
B.
The second aspect of a purported violation of privacy rights posited by the Red Cross is the potential that the questions approved by the district court will tend to harass and embarrass the donor. If the prescribed procedures were followed on February 27, 1985, the donor has already voluntarily submitted to a similarly intimate and probing interrogation.10 To the extent that avoidance of embarrassment has a constitutional dimension in this context, it only involves the embarrassment and humiliation that might follow public disclosure that the donor is infected. See Belle Bonfils Mem. Blood Ctr. v. District Court, 763 P.2d 1003, 1012-13 (Col.1988). Embarrassment and feelings of harassment flowing from the very act of answering the questions simply do not implicate a protectable interest under the Constitution.11 Cf. Whalen, 429 U.S. at 602, 97 S.Ct. at 878 (disclosure of private medical information to state health employees not “meaningfully distinguishable from a host of other unpleasant invasions of privacy that are associated with many facts of health care”). At most, the invasion of the donor’s privacy is minimal, and this interest is greatly outweighed by the plaintiff's need for the information and the related public interest in seeing that injuries are compensated.
IV.
Red Cross makes the patently disingenuous argument that direct donor discovery should be prohibited because it will only generate irrelevant, inadmissible evidence. Despite the Red Cross’s painstaking efforts to trivialize the approved interrogatories, the fact remains that there is only one person with any chance of remembering the details of that day over six years ago, and that person is the donor. We cannot help but think that the very asking of the questions, because it involves contact with the donor by someone other than the Red Cross, may indeed lead to the revelation that the donor is willing to testify at trial. In any event, we do not believe that the district court abused its discretion in approving the particular questions in its protective order.
A related attack on the relevancy of the questions is that they focus largely on the donor’s thought processes and motivations. The Red Cross correctly frames the relevant liability issue as being whether the blood donor center followed its prescribed procedures in screening the implicated donor.12 The approved questions can be grouped into three general categories:
(1) events of the specific screening process (questions 5, 9(a), 10, 11, 12, 16);
(2) the donor’s history of blood donations/deferrals (questions 1, 7);
(3) the donor’s motivations and thought processes (questions 2, 3, 4, 6, 8, 9(b and c), 17); and
(4) the donor's personal (non-donation-related) history (questions 13, 14, 15, 18).
The Red Cross only disputes the relevancy of the third and fourth categories.13 We *489review this issue of relevancy in the context of Fed.R.Civ.P. 26 for abuse of discretion.
The benchmark employed by the district court is whether the requested information “appears reasonably calculated to lead to the discovery of admissible evidence.” Fed.R.Civ.P. 26(e)(1). On relevancy matters, the trial court has broad discretion. See generally 4 Moore’s Federal Practice ¶ 26.56[1] (1989 and 1990-91 Cum.Supp.).
The inquiries into the implicated donor’s reasons for not donating blood in the past and into his knowledge of AIDS-related risks does not strike us as irrelevant under Rule 26’s “reasonably calculated” standard. The donor’s knowledge of AIDS-related risks may prompt memories of having been told of such risks during a prior donation attempt, or he may remember receiving assurances during a prior donation attempt that incarceration or homosexuality were not disqualifying circumstances. Likewise, questions about his level of education bear on the screening process; if he was obviously illiterate, the regular screening process should have been explained orally. An oral explanation would probably have taken longer than if he were able to read the information, and. the duration of the entire process might be relevant to the question of the adequacy of the procedures employed on February 27. We find no abuse of discretion.14
CONCLUSION
Acceptance of the Red Cross’s arguments would amount to a grant of virtual blanket immunity from donation-related liability. The plaintiff is seeking information about events that occurred more than six years ago, from the only person who might remember. There can be no question that what happened during the donor screening process is crucial to the plaintiff’s claim that the Red Cross was negligent in failing to defer the implicated donor. Whatever privacy interests that are involved are protected by the district court’s order. The contention that this discovery will contribute to a decline in the adequacy or the safety of the blood supply is a matter of some dispute, but we cannot say that the district court’s findings are clearly erroneous. We believe the limited discovery approved by the district court should proceed.
AFFIRMED.

IT IS SO ORDERED.
DAVID C. NORTON United States District JudgeFebruary 6, 1991
. The action was initially filed in state court in South Carolina. It was removed to federal court by the Red Cross. On January 13, 1992, after argument was heard on this appeal, this case was placed in abeyance pending the Supreme Court’s resolution of the issue of the *484federal court’s original jurisdiction over cases to which the Red Cross is a party. The Court has recently held that the Red Cross charter confers such jurisdiction. American National Red Cross v. S.G., — U.S. -, 112 S.Ct. 2465, 120 L.Ed.2d 201 (1992). The order holding this case in abeyance is therefore vacated.
. The date of the donation is still a matter of some dispute. The donation card carries a February 27, 1985, date, while the hospital blood inventory record shows a donation date of February 26, 1985. For clarity’s sake, we will refer to February 27 as the donation date. We do not intend to take a position on any factual dispute about the actual date of donation.
. Because these “interrogatories” are directed at a non-party, they are more properly characterized as “depositions upon written questions," Fed.R.Civ.P. 31. See Belle Bonfils Mem. Blood Ctr. v. District Court, 763 P.2d 1003, 1013-14 (Col.1988) (construing analogous state rules).
. The court’s protective order in Watson v. Medical University of South Carolina, C/A No. 88-2844-18 (D.S.C. Feb. 7, 1991), is reproduced in the Appendix to this opinion.
. See Note, Transfusion-Related AIDS Litigation: Permitting Limited Discovery from Blood Donors in Single Donor Cases, 76 Cornell L.Rev. 927 (1991), for a thorough and up-to-date compilation of the cases and articles on this subject.
. We note that scientific advances in testing for the presence of the HIV antibody should serve to significantly reduce the number of donation-related cases in the future. Only weeks after Trevor received the transfusion of the implicated donor's blood, the Food and Drug Administration approved the first such test. See Rasmussen, 500 So.2d, at 537 n. 10.
. The nation also has a stake in seeing that victims of negligence are fully compensated by the responsible party. See Belle Bonfils, 763 P.2d, at 1012.
. This reasoning applies only to voluntary donors. Paid “donors" have different incentives to give blood, and we strongly suspect that their level of candor in screening is governed primarily by the going price.
. We leave for another day the question of whether court-approved disclosure to a larger universe might violate the donor’s privacy rights.
. For instance, a prospective donor in 1985 was asked by the screening nurse whether he or she (the donor) had ever taken self-injected drugs or been exposed to anyone with AIDS.
. Although the question certified to this court includes a reference to the Constitution of South Carolina, the Red Cross makes no argument that the state constitutional protection of the right to privacy, embodied in S.C. Const, art. I § 10, is any broader than the federal constitutional right.
. An independent basis for liability, one not involved in this appeal, is whether the prescribed procedure itself was adequate.
. In its opening brief, the Red Cross includes question 1 among the purportedly irrelevant interrogatories. Question 1 asks about the total *489number of donations by the donor; this is clearly relevant inasmuch as it may lead to other records pertaining to the donor.
. The Red Cross also argues that the approved method of discovery is not authorized by the rules of civil procedure. Rule 31, as modified by the protective order entered pursuant to the provision of Rule 26(c), is clearly ample authority for the court’s protective order. See note 2, supra.
