Argued telephonically March

Before Judges Keefe, Eichen and
Steinberg.
On appeal from the Superior
Court of New Jersey, Law Division, Essex County, L-11230- 95.
Gregg F. Paster argued the cause
for appellants (Ortiz & Paster, attorneys; Mr. Paster, on the brief).
Roger G. Ellis argued the cause
for respondent (Bumgardner & Ellis, attorneys; Mr. Ellis and Alyson C. Douma,
on the brief).
No other parties participated in
this appeal.
The opinion of the court was
delivered by
EICHEN, J.A.D.
Plaintiffs' decedent died of cirrhosis of the liver
on October 1, 1993. Plaintiffs contend that decedent acquired the condition as
the result of receiving a blood transfusion tainted with the hepatitis B virus
in 1983. Defendant North Jersey Blood Center (NJBC) denies that the decedent
received tainted blood, and argues that even if it was tainted, the blood center
employed the testing procedures utilized by most blood centers at the time the
blood was donated and, therefore, it is not liable to plaintiffs.
Plaintiffs premised their wrongful death action against
the blood bank on the theory that the blood bank was negligent in failing to
employ the hepatitis core antibody test in 1983. Plaintiffs maintain that test
was available and would have reduced the risk of failing to detect latent
hepatitis B, as compared with the surface antigen test used by NJBC, which
plaintiffs allege failed to detect the virus.See
footnote 11 Accordingly, it was plaintiffs' burden to prove that
NJBC was negligent in failing to use the core antibody test; that its negligence
enhanced the risk that decedent would contract hepatitis B; and that the
enhanced risk was a substantial factor in causing her injury. Snyder v.
Mekhjian, 244 N.J. Super. 281, 293 (App. Div. 1990) (Snyder I),
aff'd o.b., 125
N.J. 328 (1991).
This appeal basically addresses two issues: The first
issue requires us to decide whether the court erred in denying plaintiffs'
motion for further discovery of the blood donors, specifically, discovery of
their identities for the purpose of retesting them for the presence of the
virus. The second issue requires us to determine whether the judge erred in
instructing the jury on the applicable standard of care with respect to NJBC's
conduct in testing the blood used in decedent's transfusion for the hepatitis B
surface antigen: a modified professional negligence (medical malpractice)
standard or an ordinary due care negligence standard.
Prior to trial, a Law Division judge denied plaintiffs'
discovery request. At the conclusion of the trial, a different Law Division
judge rejected plaintiffs' request for an ordinary, "reasonable
persons" negligence jury instruction and gave a modified medical
malpractice charge on the standard of care applicable to the blood center. A
jury found no negligence against NJBC and returned a verdict in its favor. This
appeal then ensued.
On appeal, plaintiffs contend that the trial court erred
(1) in denying plaintiffs' motion seeking discovery of the donors' identities;
(2) in giving a professional negligence charge rather than a standard negligence
charge to the jury; and (3) in the wording of the verdict sheet with respect to
the issue of proximate cause.
We summarize briefly the background evidence adduced at
trial. In May 1983, following a diagnosis of cervical cancer, plaintiffs'
decedent Ernestine Elkerson underwent a hysterectomy at the University of
Medicine and Dentistry of New Jersey (UMDNJ). Several months later, in October
1983, UMDNJ diagnosed Ms. Elkerson as positive for infection with the hepatitis
B virus. The decedent received treatment at UMDNJ for the condition for several
years following her diagnosis. In 1990, the plaintiffs' decedent tested positive
for the hepatitis B delta virus. On October 1, 1993, she died of cirrhosis of
the liver.
Plaintiffs filed their complaint on September 18, 1995.
Named as defendants in the action were New Jersey Blood Center (NJBC), UMDNJ,
and the American Association of Blood Banks (AABB).See
footnote 22 The amended complaint alleges that the decedent
contracted hepatitis B with delta virus (hepatitis D) as a result of a blood
transfusion administered to her during her admission to UMDNJ in 1983. During
that admission, Ms. Elkerson received four units of packed red blood cells and
frozen plasma, three of which UMDNJ obtained from NJBC.See
footnote 33 Prior to distributing these units, NJBC tested the
blood for hepatitis B with the surface antigen test and none of the blood tested
positive for the virus.
We address first the discovery issue. During pre-trial
discovery, plaintiffs received redacted donor cards, completed questionnaires
and a checklist and physical examination notes from medical personnel at the
blood center with respect to the blood donors. Based on that, plaintiff moved to
compel defendant to disclose their identities and addresses.
On the motion to compel, plaintiffs argued that they
wanted the discovery so that the court could contact the donors to determine if
they would be willing to answer some additional questions and submit an
additional blood sample.See footnote 44
This request was based on the theory that if these donors tested negative for
the hepatitis virus now, they would have tested negative in 1983, thereby
obviating the need for continuing the lawsuit.
Defendant NJBC countered that the plaintiffs had not
established a sufficient need for the information in order to overcome the
donors' privacy interests. NJBC also argued that the type of hepatitis that
plaintiffs' decedent was diagnosed with, hepatitis B with a delta virus, would
have been detected by the surface antigen test performed by the blood bank had
it been present and, therefore, core antibody testing was unnecessary.See
footnote 55
The trial court denied plaintiffs' motion, in part,
because plaintiffs were not challenging the blood center's screening method as
in Snyder I; plaintiffs failed to demonstrate a "particularized
need"; and on balance, plaintiffs' right to obtain the identities of the
donors did not justify such intrusion into the privacy of the donors.
Our courts have weighed the potential adverse effects to
the blood collection system and the donors' privacy interests against a
plaintiff's need for discovery so that victims of contaminated blood have an
opportunity to recover in this type suit. See Snyder I, supra,
244
N.J. Super. 281; see also Snyder v. American Ass'n of Blood Banks,
282
N.J. Super. 23 (App. Div. 1995) (Snyder II), aff'd 144
N.J. 269 (1996); Doe v. Greater New York Blood Program, 304
N.J. Super. 287 (App. Div. 1997).
In balancing those interests in this case, we conclude
that identifying the donors now for the purpose of re-testing them with the core
antibody test does not justify overcoming the privacy interests of the donors or
the blood bank industry's interest in protecting a continuing source of blood
product. That is because testing for the virus now would not provide sufficient
evidence to prove that tainted blood furnished by NJBC caused decedent's
hepatitis, even giving plaintiffs the benefit of all favorable inferences.See
footnote 66
We recognize that proving a causal relationship between
the blood received by plaintiffs' decedent and her acquisition of hepatitis is
an important element of plaintiffs' cause of action, an element on which
plaintiffs have the burden of proof. However, eighteen years have passed since
the decedent received the allegedly tainted transfusion. Given the time lapse,
even if re- testing of the three NJBC blood donors produced positive reactions
for the hepatitis B delta virus, there still is no way for any reasonable
fact-finder to conclude that the donors were carriers of the virus back in 1983.See
footnote 77
Dealing as we are then with less than a
"possibility" that the donors were reactive for the virus in 1983, we
must weigh the conflicting interests in favor of protecting the blood bank's
need for a continuing source of blood supply and the donors' privacy interests
against plaintiffs' need to know the donors' identities. As we said in Snyder
I, the "confidentiality of blood bank ... records rests upon
significant public and private considerations and is ordinarily essential to
assure the continued effectiveness of the screening process, the willingness of
donors to continue to participate in blood collection efforts, and the general
integrity of the nation's blood programs." Snyder I, supra,
244 N.J. Super. at 296. Accordingly, we affirm the order denying
discovery of the donors' identities.
We turn next to the jury charge on negligence and
conclude that the trial judge erred in instructing the jury on the standard of
conduct applicable to blood centers. Therefore, we reverse the judgment.
Plaintiffs submitted an enhanced risk charge requesting the court to explain
negligence to the jury by using an ordinary negligence standard. That standard
would have permitted the jury to determine how a reasonably prudent blood bank
should have performed under the circumstances and would have allowed the jury to
analyze NJBC's testing procedure under that standard. Specifically, plaintiffs
requested the court to tell the jury that "[b]lood banks in New Jersey are
required to take all measures and precautions which a reasonable and prudent
blood banker would have taken at the time period referred to in this case,
specifically, Spring of 1983."
The court rejected the proposed charge because it viewed
the collecting and processing of blood as a skilled medical service,
determining, therefore, that NJBC should be treated as a medical professional.
Consequently, the court gave a modified medical malpractice charge to the jury
essentially instructing it that if NJBC conformed to the generally recognized
and accepted practices in the blood bank industry, it could not find NJBC
negligent. The court told the jury that NJBC was a health care provider and,
therefore, represents that it "possess[es] that degree of knowledge, skill
and care which is possessed and used by the average Blood Bank." It then
told the jury that "[t]he required knowledge, skill, and care must be
judged by the standard practice of blood banking in April of 1983."
(Emphasis added.)
The court iterated this custom-based standard of care
several times throughout the charge. Specifically, the court told the jury that
[t]he law does not require that
a Blood Bank guarantees a favorable result. The law recognizes that the practice
of Blood Bank medicine, according to standard medical practice, will not
necessarily prevent the poor result. If the Blood Bank has brought and applied
the required knowledge, skill, and care to the patient, it is not liable or
responsible simply because a bad result has occurred.
Now the obligation or duty of
care in which the law imposes upon a Blood Bank is to bring to its patient that
knowledge, skill, and care which are ordinarily possessed and exercised in
similar situations by the average member of the profession in its field. The
Blood Bank is obliged to use its knowledge and skill in an effort to care for
its patient according to standard medical practice.
If you find that the defendant
Blood Bank has complied with this standard, it is not negligent and, therefore,
not liable to the plaintiff estate regardless of the result.
On the other hand, if you find
that the Blood Bank has departed from the standard of care resulting in the
occurrence complained of, then you should find the defendant negligent or
responsible to the estate to respond in damages.
On appeal, plaintiffs make the following arguments
concerning the jury charge with which we concur. They argue that the charge
virtually guaranteed a finding of no negligence on the part of the blood center
because the evidence disclosed that NJBC, like virtually all blood banks, used
the surface antigen test and not the core antibody test in 1983, thus
establishing the standard of conduct or practice in the blood bank industry as
the surface antigen test, even though the Center for Disease Control (CDC)
recommended core antibody testing as early as January 1983. See Snyder
I, supra, 244 N.J. Super. at 288. Plaintiffs assert that such
a custom-based standard cannot be correct because satisfaction of that standard
alone in this case could be seen as unreasonable and, therefore, negligent.
Thus, under a custom-based system, NJBC could insulate itself from liability by
simply conforming its practices to what was uniformly done by most blood banks,
even though more reliable testing methods were available at the relevant time.
Plaintiffs insist that such a result is contrary to the principles established
in Snyder I and Snyder II. As noted, we agree and would reverse
the judgment but for plaintiffs' failure of proof on the causation issue.
Evidence of the custom or practice of a particular
industry does not conclusively dispose of the issue of the proper standard of
conduct, see Wellenheider v. Rader, 49
N.J. 1, 7 (1967), even though a blood bank must exercise special knowledge
and skill. "The standard of conduct is reasonable care, that care which a
prudent [person] would take in the circumstances." Ibid. Quoting
Dean Prosser, the Court explained:
Even an entire industry, by
adopting such careless methods to save time, effort or money, cannot be
permitted to set its own uncontrolled standard.... And if the only test is to be
what has been done before, no industry or group will ever have any great
incentive to make progress in the direction of safety.... Much the better view,
therefore, is that of the great majority of the cases, that every custom is not
conclusive merely because it is a custom, and that it must meet the challenge of
"learned reason," and be given only the evidentiary weight which the
situation deserves. It follows that where common knowledge and ordinary judgment
will recognize unreasonable danger, what everyone does may be found to be
negligent; and that there will be extreme cases where it is so clearly negligent
in itself that it may even be excluded from evidence.
[Wellenheider, supra,
49 N.J. at 7-8 (quoting Prosser, Torts ' 33, 170 (3d ed. 1964)).]
Even if its services are integral to those of health
care providers such as hospitals and doctors, to allow the blood bank industry
to set its own standard of conduct is tantamount to allowing it to set the
limits of its own legal liability, even though those limits are below a level of
care readily attainable. See United Blood Servs. v. Quintana, 827
P.2d 509, 520 (Colo. 1992). Hence, if the blood bank industry is allowed to
establish its own custom or practice of testing for the presence of an
infectious disease, then no matter how unreasonable such standard might be by
ordinary judgment, all members of the blood bank industry would be insulated
from liability as long as they conformed their practice to the industry's
self-established norm. This result is not tolerable in our system of justice.
The standard is not what test the average member of the blood bank industry used
to screen for the hepatitis B virus in 1983, but what test a reasonable blood
bank should have used given reasonably available testing alternatives at the
relevant time.
Hence, "when a risk is obvious and a precautionary
measure available, an industry or professional standard or custom that does not
call for such precaution is not conclusive, if, regardless of the standard or
custom, the exercise of reasonable care would call for a higher standard." Klimko
v. Rose, 84
N.J. 496, 506 n.4 (1980).
The trilogy of blood bank cases decided by this court
support this conclusion. Snyder I, supra, 244
N.J. Super. 281; Snyder II, supra, 282
N.J. Super. 23; Doe, supra, 304
N.J. Super. 287. In Snyder I, the plaintiff contracted HIV following
an infusion of blood during surgery to repair a bleeding artery. Plaintiff filed
suit against the doctors and the blood bank based on theories of both strict
liability and negligence. The claim against the blood bank alleged that it
"greatly enhanced [plaintiff's] risk of receiving contaminated blood by
failing to prescribe and implement available risk-reducing procedures in the
blood-collection process" and that the bank "negligently failed to
follow such screening procedures as it did then have in place." Snyder I,
supra, 244 N.J. Super. at 286. The blood transfusion in that case
occurred in August 1984; HIV was identified as the cause of AIDS in April 1984;
and, by March 1985, tests were available to screen blood for the presence of
HIV.
The plaintiff's expert alleged that the performance of
core antibody testing probably would have led to the rejection of the donor's
blood. The trial court denied the plaintiff's request for further information
concerning the donor.See footnote 88
We reversed the trial court's denial of plaintiff's discovery request. Id.
at 297. In the course of our decision, we noted that there was a factual
question as to the appropriateness of the blood bank's conduct, irrespective of
its compliance with the guidelines of the AABB respecting screening procedures
in effect at the time. Id. at 293. In so noting, we acknowledged our
willingness to evaluate the reasonableness of a blood bank's conduct,
notwithstanding what other blood banks might be doing to safeguard their blood
supply. We reached the same conclusion in Snyder II where we applied the
reasonableness and ordinary prudence standard in analyzing the duty of the AABB
in establishing appropriate guidelines for screening and testing for
HIV-positive donors. Snyder II, supra, 282 N.J. Super. at
43-44.
In Doe, supra, 304
N.J. Super. 287, plaintiff tested HIV- positive after receiving a blood
transfusion from the Greater New York Blood Program in February 1982. It was not
until seven years after plaintiff's transfusion that a screening revealed that
the donor was HIV-positive. Defendant then performed a "look-back" and
notified plaintiff of the problem.
Defendant moved for summary judgment. The judge reviewed
the experts' certifications and medical studies as well as various federal and
state decisions addressing the question of whether blood banks had a duty to
screen for HIV between 1982 and 1985. Id. at 296. The trial judge
emphasized that as of August 1981 the CDC reported that transmission of the HIV
virus was thought to occur through seminal fluid, not through blood products. Ibid.
The judge also observed that "not one decision found a duty for a blood
bank to high risk screen or surrogate test prior to March of 1983." Ibid.
Noting that plaintiff received the blood transfusion thirteen months before any
blood testing for HIV was being recommended, and eighteen months before the
transfusion in Snyder I, the judge granted summary judgment, concluding
that "rational minds simply could not differ" on the issue of whether
"the blood bank industry had a duty to high risk screen and/or surrogate
test in February of 1982." Ibid.
We agreed and affirmed the summary judgment on that
point. However, we "part[ed] company from" the judge with respect to
whether the blood bank could be viewed as acting unreasonably when it failed to
screen for other infectious diseases that might have resulted in
rejection of the donor's blood, despite the fact that it may have "complied
with all applicable professional standards of care, including [existing] federal
and state regulations in January 1982." Id. at 298 (emphasis added).
As is evident from our decision in Doe, we considered the blood bank's
duty of care not in terms of the national standards actually being utilized by
blood banks across the country, but by analyzing the reasonableness of the blood
bank's conduct given the available testing measures that could have rejected
this donor's blood for other reasons. Even as early as Brody v. Overlook
Hospital, 66
N.J. 448, 450 (1975), the Supreme Court remarked outright that a blood bank
was under an "obligation to use due care."
In sum, these blood bank cases clearly indicate that the
standard of care for judging the conduct of blood centers and related groups is
the ordinary, reasonable care standard, not the custom-based standard of conduct
the trial court used in this case. This custom-based charge had the clear
capacity to affect the result of the trial, especially when viewed in light of
plaintiffs' expert's testimony.
Plaintiffs provided expert testimony from Dr. Donald P.
Francis, M.D., an expert in the fields of epidemiology and virology,
specifically with regard to hepatitis, blood transmission disease and the
screening of high risk donors in a blood bank setting. Dr. Francis opined that
by not performing core testing in April 1983, NJBC's conduct was not
"reasonable and prudent." He determined that had core testing been
used, a low level carrier donor would have been screened out. Dr. Francis also
opined that all blood banks should have been using core testing in 1983, noting
that "[t]he fact that one is acting poorly or the whole group is acting
poorly doesn't excuse any of them."
Dr. Francis's qualifications were extensive. He received
his medical degree from Northwestern Medical School in Chicago and a doctorate
in virology from the Harvard School of Public Health. Dr. Francis was employed
by the CDC from 1971 to 1992 where he worked on hepatitis and AIDS, among other
infectious diseases. Dr. Francis supervised the first AIDS laboratory at the CDC
from 1981, the beginning of the AIDS epidemic, until 1992. In addition, he
served as the AIDS advisor to the State of California and chaired the San
Francisco Mayor's HIV Task Force. Since 1992, he has been working on an AIDS
vaccine in private industry. Dr. Francis also published numerous medical
articles, half of which concern hepatitis.
Dr. Francis testified that hepatitis B is a viral
infection causing inflammation of the liver. Ten percent of individuals who
develop hepatitis become chronic carriers of the virus. This 10% includes
"low level" carriers of the virus, those who test negative but are
still infectious.
Dr. Francis also testified that plaintiffs' decedent
manifested hepatitis symptoms about four months after her blood transfusions,
which he opined was a normal incubation period. He further asserted that the
test used by NJBC, the hepatitis B surface antigen test, is a "good test
but not perfect" because there are a small group of carriers who will test
negative with the surface antigen test. In contrast, Dr. Francis opined, the
core antibody test "will cover all of these individuals who are infected
with hepatitis B."
Dr. Francis described how, in January 1983, he
personally tried to get the blood bank industry to use the core antibody test.
At that time, he was the assistant director for the hepatitis division of the
CDC. Dr. Francis explained that 1983 "was a time when AIDS was emerging and
that the hepatitis B core test was also recommended as a useful test to screen
out individuals at risk of AIDS." According to Dr. Francis, "the major
group who w[as] transmitting AIDS by blood transfusions were homosexual men, and
they ha[d] a very high rate of the hepatitis B infection."
Dr. Francis stated that on January 4, 1983, he addressed
an emergency meeting at the CDC attended by "a large representation of the
blood banking and plasma collection industries," including the AABB, the
Red Cross, and other blood banking organizations, to discuss transfusions and
the AIDS problem. Dr. Francis testified that at the meeting, "as an officer
of the Public Health Services and Center for Disease Control," he
recommended "that blood banks screen out all donors who were infected with
hepatitis B, using the core antibody test to exclude all individuals who were
infected with hepatitis B." Dr. Francis further stated, however, that
"[t]here was a reluctance of the blood banking industry to accept the
reality [that] there was such a thing as transfusion-associated AIDS, and as a
result, [a] reluctance to take aggressive action to prevent it."See
footnote 99
The report that evolved from that January 1983 CDC
emergency meeting recommended that blood banks begin evaluating core antibody
testing. However, NJBC did not begin using core testing until December 1986,
while the AABB did not begin recommending its use until 1987.
Aided by the foregoing expert evidence to guide its
determination concerning the reasonableness of NJBC's conduct in failing to use
the core antibody test in plaintiffs' decedent's case, we believe that a
properly instructed jury reasonably could conclude that, irrespective of the
custom in the blood bank industry in 1983, exercise of reasonable care required
NJBC to use the core antibody test at that time. However, instead of applying
this reasonable care standard, the court directed the jury to accept the
experts' opinions as to what was the ordinary custom in the industry in 1983 and
to use that as its standard to determine whether the blood center was negligent.
Nowhere in the charge is there any direction that allowed the jury to question
the reasonableness of the custom or practice employed by the industry. Where, as
here, the industry standard could be viewed as falling below ordinary care, the
jury should have been instructed it could reject that custom as the standard, in
light of Dr. Francis' testimony, and reach its own conclusion based on what is
reasonable under all the circumstances.
In sum, the trial court's negligence charge constitutes
reversible error because it did not allow the jury to reject the industry
standard applied uniformly by blood banks in 1983 in favor of its own
expert-informed judgment in determining whether that custom was or was not
reasonable. In light of the expert evidence that a more effective test was
available to screen out blood tainted by the hepatitis B virus in April 1983, we
are convinced that the erroneous charge was capable of producing an unjust
result.
In the interest of completion, we address briefly
plaintiffs' claim of error directed to the verdict sheet.
The first three interrogatories on the verdict sheet
read as follows:
1. Was
defendant North Jersey Blood Center negligent?
_____YES _____NO
If NO return your Verdict
If YES go to #2
2. Did
defendant North Jersey Blood Center's negligence unreasonably create an
enhancement of Ernestine Elkerson's risk of contracting hepatitis?
______YES ______NO
If NO return your
Verdict.
If YES go to #3
3. Was
the enhanced risk a substantial factor in producing Ernestine Elkerson's
contracting Hepatitis?
______YES ______NO
If NO return your
Verdict.
If YES go to #4.
(Emphasis added.)
During the charge conference, plaintiff objected to the
use of the term "unreasonably" in the second interrogatory concerning
proximate cause as redundant. Plaintiffs argued that the use of the term was
redundant because the interrogatory required the jury to find negligence twice.
Defendant argued that the language mirrored the language in Snyder I,
and, therefore, should be included. Agreeing with defendant, the trial court
ruled that the verdict sheet should read the way it was presented.
We agree that the verdict sheet was improper in using
the word "unreasonably" in the second interrogatory. The use of the
word imposed a double burden on plaintiffs to prove that NJBC's conduct was
negligent, i.e., unreasonable, because an affirmative response to the
first interrogatory already required the jury to consider whether NJBC acted
unreasonably. Hence, the word "unreasonably" should have been deleted
from the interrogatory.
Affirmed, in part; reversed, in part; and remanded for
further proceedings not inconsistent with this decision.
Footnote: 1 1
Although plaintiffs also alleged in their amended complaint that NJBC
"negligently failed to adequately screen the blood supply for hepatitis
B," their expert's opinion did not provide a factual basis to support that
claim, the expert's primary focus being on the inadequacy of the testing methods
used by the blood bank in April 1983.
Footnote: 2 2
Prior to trial, the court granted summary judgment to UMDNJ. The record is
unclear as to the status of AABB as a party to the suit but we assume it was
dismissed because the case was submitted to the jury with NJBC as the sole
defendant.
Footnote: 3 3
The fourth unit was collected by the Blood Bank of the Alameda-Contra Costa
Medical Association in Oakland, California. Plaintiffs did not name this entity
as a defendant in this action.
Footnote: 4 4
Plaintiffs were willing to have the court act as a conduit for the information
in order to protect the donors' confidentiality.
Footnote: 5 5
Notably, both plaintiffs' and defendant's experts agreed that hepatitis D
increases the level of hepatitis B surface antigen in the blood. Defendant's
expert contended that, as a result of this phenomenon, the surface antigen test
would have detected the hepatitis B surface antigen in the donors' blood had it
been present. Plaintiffs' expert agreed that the hepatitis B and D viruses are
"piggyback" viruses and that a person with the hepatitis delta will
normally test positive with the hepatitis B surface antigen test, but that
"always is not the case," and "a few percent ... will slip under
the screening test detection line."
Footnote: 6 6
Compare Snyder II where the donor acquired AIDS in 1986, two years
after the original test. They were tested again in 1994. In those circumstances,
this court was willing to draw the inference that the donors would have tested
HIV-positive two years earlier had the available core testing been used in 1984.
Footnote: 7 7
It also should be recalled that the fourth donor's blood originated in a
California blood center which was not named as a defendant in this action,
providing another reason why testing NJBC's donors at this late date would be
even less definitive.
Footnote: 8 8
Similar to this case, the plaintiff in Snyder I had already received the
registration form of the donor, which consisted of a questionnaire and previous
blood donation and vital signs at the time of the donation. All identifying
information was redacted. Id. at 294.
Footnote: 9 9
Dr. Francis gave even more compelling testimony on this point in our previous
blood collection cases. See Doe, supra, 304 N.J. Super.
at 90-92; Snyder II, supra, 282 N.J. Super. at 32-34.
