This test looks for HIV infection in your blood or saliva.
HIV is the virus that causes AIDS. About 1 in 5 people who are infected with HIV don't know it because they may not have symptoms. HIV comes in 2 forms:
-
HIV-1. This type is found worldwide.
-
HIV-2. This type is mainly found in western Africa. But it has spread to the U.S.
This test is one of several tests that look for HIV infection. Some tests take a few days for results to come back. Rapid HIV tests can give your results in about 20 minutes. Getting an early diagnosis of HIV is important because you can start treatment early and also take steps to keep from spreading the virus to others.
Normal results are negative. This means that no antibodies were found and that you may not be infected with HIV. Most people who become infected with HIV will develop antibodies to the virus within 2 months. During this time, you may have HIV, but this test can't detect it. You may need to repeat the test more than 3 months after your possible exposure if your results are negative.
