| On July 3, 2011, FDA approved the OraQuick
In-Home HIV Test, the first over-the-counter, self-administered HIV test kit
to detect the presence of antibodies to human immunodeficiency virus type 1
(HIV-1) and type 2 (HIV-2).
The OraQuick In-Home HIV Test is designed to allow
individuals obtain test results within 20 to 40 minutes using an oral fluid
sample collected by swabbing the upper and lower gums inside the mouth, then
placing that sample into a developer vial provided as part of the kit.
A positive result with this test does not mean that an
individual is definitely infected with HIV, but rather that additional
testing should be done in a medical setting to confirm the test result.
Similarly, a negative test result does not mean that an
individual is definitely not infected with HIV, particularly when exposure
may have been within the previous three months.
Not all individuals develop antibodies to HIV at the same
rate, and so it make take longer for some to develop levels of antibodies
detectable using an antibody test. This time to detectable antibody levels
is called "the window period."
The test has the potential to identify large numbers of
previously undiagnosed HIV infections, especially if used by those unlikely
to use standard screening methods.
Because knowing your status is an important factor in the
effort to prevent the spread of HIV, the availability of a home-use HIV test
kit provides another option for individuals to get tested so that they can
seek medical care.
Clinical studies for self-testing have shown that the
OraQuick In-Home HIV Test has an expected performance of 92% for test
sensitivity, the percentage of results that will be positive when HIV is
present. This means that one false negative result would be expected out of
every 12 test results in HIV-infected individuals.
Clinical studies also have shown that the OraQuick In-Home
HIV Test has an expected performance of 99.98% for test specificity, the
percentage of results that will be negative when HIV is not present. This
means that one false positive would be expected out of every 5,000 test
results in uninfected individuals.
OraSure Technologies, the manufacturer of the OraQuick
In-Home HIV Test will have a telephone consumer support center available 24
hours a day, seven days a week once the product is available for sale to the
public. The center will provide education about HIV/AIDS, the proper method
for administering the test, and guidance on what to do once results have
been obtained. Information about the consumer support center and contact
information is included in the test kit.
OraSure Technologies, Inc. is headquartered in Bethlehem,
Pa. A version of this test for use by trained technicians in clinical
settings was approved in 2004.
While the newly approved test is the first home use kit
that provides rapid results to the user, there is another FDA-approved home
test collection kit, the The Home Access® HIV-1 Test System, approved since
1996. The Home Access HIV-1 home collection test system is sold as either
"The Home Access HIV-1 Test System" or "The Home Access Express HIV-1 Test
System." It allows blood samples to be taken at home using a simple finger
stick, that people then send to a laboratory for testing, which includes
both screening and confirmation. Results are obtained by phone using an
individual identifier code supplied with the product. The sensitivity
determined in clinical studies reported is estimated to be 100% based on the
correct identification of 150/150 positive samples compared to matched serum
specimens. The specificity determined in the studies reported is estimated
to be 100% based on the correct identification of (997/997) negative samples
compared to matched serum specimens. |
