Different Types of HIV Tests
The 2 types of tests most commonly used to detect HIV infection are the ELISA (enzyme-linked immunoassay) and Western blot tests. These tests are very accurate, but they are only able to detect HIV antibodies and not the HIV virus particle itself.
- A process is followed to determine if you are HIV positive.
- First, the ELISA test is performed.
- If the ELISA test is negative for the detection of HIV antibodies, the test is reported as negative.
- If the ELISA test is positive for the detection of HIV antibodies, the ELISA test is repeated on the same blood sample.
- If the sample is repeatedly reactive by ELISA, the results are then confirmed using the Western blot test.
