FDA Approves First HIV Home Test System
The Food and Drug Administration today approved the first HIV
test system that includes collection of blood samples at home.
Until now, all HIV tests, whether using blood or saliva samples,
were done under the supervision of a health professional at medical
facilities, clinics, physicians' offices or blood establishments.
The new testing system is comprised of three integrated
components: an over-the-counter home blood collection kit, HIV-1
antibody testing at a certified lab, and a test result center that
provides test results, counseling and referral anonymously.
The test kit system is called the Confide HIV Testing
Service, developed and marketed by Direct Access Diagnostics, a
subsidiary of Johnson and Johnson, Bridgewater, N.J.
More than 60 percent of Americans at risk for contracting HIV
have not been tested, according to estimates by the Centers for
Disease Control and Prevention.
"Too many Americans do not know their HIV status. Knowledge
is power, and power leads to prevention," said HHS Secretary Donna
E. Shalala. "The availability of a home test should empower more
people to learn their HIV status and protect themselves and their
loved ones."
"We are confident that this new home system can provide
accurate results while assuring patient anonymity and appropriate
counseling," said Commissioner of Food and Drugs David A. Kessler,
M.D. "Science and technology have evolved to the point where we
believe the benefits of this new product outweigh the risks."
Technological advances in the accuracy of HIV antibody
testing, the availability of treatments for people who are infected
but do not yet have symptoms, and the public health benefits that
would accrue from more people being aware of their HIV status all
contributed to the agency's decision to approve the kit for home
use. The decision is consistent with advice that FDA received at
a June 1994 meeting of FDA's Blood Products Advisory Committee. At
that meeting, the committee concluded that the potential benefits
of over-the-counter home specimen collection kits outweighed the
potential risks.
After purchasing a kit, a person begins the testing process
by reading a pre-test counseling booklet about HIV and AIDS. Using
enclosed lancets, the person takes a finger stick blood sample
which is placed on a designated area of a test card precoded with
a unique identification number.
The test card is mailed in a protective envelope to a
certified laboratory for HIV-1 antibody testing. Once instructions
are followed and an adequate sample has been sent, people can
receive results seven days later by calling a toll-free number.
The lab testing process is consistent with FDA recommendations
for blood and plasma establishments. Any initially reactive sample
is retested twice. Samples reactive in two out of three assays are
further confirmed with a more specific test, such as the Western
blot.
To get results, patients call the Confide Test Result Center
and give their identification number from the test kit.
Professional, certified counselors who speak both English and
Spanish notify callers of the results if they are positive or
inconclusive. Local medical referrals are provided if needed and
those who test positive are encouraged to seek medical care. All
conversations are anonymous and confidential.
Although negative results are provided by an automated
message, everyone has the opportunity to speak to a counselor. All
negative test results include an explanation of the "window"
period, the time when people may be HIV-infected but still have
negative antibody tests. The window period, in most cases, lasts
approximately 1 month.
FDA's approval was based on data showing that each component
of the test system, as well as the complete system itself, was safe
and effective for its intended use. Clinical studies showed that
the Confide Test Card was able to correctly identify negative
samples 99.95 percent of the time based on evaluations of over
3,940 samples. The test also correctly identified 100 percent of
150 known positive samples.
Initially, the company will make the kit available for over-
the-counter purchase in the state of Texas. Residents of Texas
and Florida who would prefer having the kit mailed to their homes
can obtain them through a toll-free number.
