Antibody tests can take 23 to 90 days to detect HIV infection after an exposure.

What is the window period for HIV test results?

• The window period varies from person to person and also depends upon the type of HIV test. Most HIV tests, including most rapid tests and home tests, are antibody tests.

What happens if my HIV test is negative 3 months later?

• If you get an HIV test within 3 months after a potential HIV exposure and the result is negative, get tested again in 3 more months to be sure.
