HIV TestingThe only way to know whether you have HIV is by having an HIV test. A test sample is taken to look for HIV antibodies, which are produced when a person is infected with HIV. ACT NOW if it has been less than 72 hours since a possible exposure to HIV. You can take medication to prevent becoming HIV positive.

The Window Period
- The window period is the time between exposure to HIV and when the body has produced enough antibodies to the virus to be detected by an HIV test.
- During the window period, an infected person is very contagious and can transmit the HIV virus to others.
- The average time for detectable antibodies to develop is 25 days after infection.
The HIV Test
If you first HIV test is negative, continue taking steps to prevent HIV, like using condoms or taking PrEP. Ask your provider about when to get tested again. If your test is positive, go to a provider to have a follow up blood draw to confirm this result.
If this test is positive, talk to your provider about starting treatment right away. HIV infection is a treatable illness. If it is negative, continue taking precautions.
Types of Tests
Home Test - available online or from pharmacy, oral swab detects HIV infection 3 months after exposure, results available in 20 minutes, results are highly accurate, but positive results must be confirmed by a blood draw through your provider.

Rapid Test - Available from a health department or community based organization, oral swab or finger stick detects HIV infection 3 months after exposure, results available in 20 minutes. Results are highly accurate, but positive results must be confirmed through a blood draw by your provider. Free or low cost.

Traditional Blood Draw - Available from your provider, a blood specimen is sent to a laboratory. HIV infection detected 1-3 months after exposure depending on the test.
