The United States announced Tuesday that it had authorized the first over-the-counter home testing kit for HIV, the virus that leads to acquired immune deficiency syndrome (AIDS).

Under the testing procedure, the OraQuick In-Home HIV test kit will allow purchasers to collect an oral fluid sample by swabbing the upper and lower gums inside of their mouths, the Food and Drug Administration (FDA) announced.

The sample is placed into the kit’s developer vial and results should be available within 20 to 40 minutes.

The FDA noted that a positive result from the test does not mean a person is definitely infected with HIV (human immunodeficiency virus), but rather that an additional test
should be done in a medical setting to confirm the 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,” the FDA said in a statement.

The home testing kit has the potential to identify large numbers of previously undiagnosed HIV infections, especially if used by those unlikely to use standard screening methods, according to the FDA.

The Centers for Disease Control and Prevention estimates that 1.2 million people in the United States are living with HIV infection — of which about one in five are not aware they are infected.

There are about 50,000 new HIV infections every year and many of those infections are transmitted from people who are unaware of their HIV status.

“Knowing your status is an important factor in the effort to prevent the spread of HIV,” said Dr Karen Midthun, director of the FDA’s Center for Biologics Evaluation and Research.

“The availability of a home-use HIV test kit provides another option for individuals to get tested so that they can seek medical care, if appropriate,” she added.

Clinical studies for self-testing have shown that the OraQuick home HIV test has an expected performance of 92 percent for test sensitivity, the percentage of results that will be positive when HIV is present, said the FDA statement.

“This means that one false negative result would be expected out of every 12 test results in HIV-infected individuals,” it added.

Similar testing indicates that one false positive would be expected out of every 5,000 test results in uninfected individuals, according to the FDA, which is responsible for regulating medication in the United States.
