HIV-1/2 Fourth Generation Test
Human immunodeficiency virus, or HIV, is a sexually transmitted infection (STI) that damages the immune system. This makes it easier to get sick and even die from infections or diseases that the body could normally fight off.
This test checks your blood for two types of HIV: HIV-1 and HIV-2. HIV-1 is the most widespread around the world.
After being infected with HIV, it can take several weeks or months for blood tests to detect the virus. If you test too soon, the test may be negative even if the virus is in your body. If you think you may have been exposed to HIV, you should get medical help immediately. Prompt treatment within 3 days of a possible exposure can lower the chance that you’ll develop an HIV infection.
