What is the HIV testing window period?

The window period is the time between HIV exposure and when a test can reliably detect the infection. For antibody tests, this period is typically 3-12 weeks, as it takes time for the body to produce detectable antibodies. Antigen/antibody tests can detect HIV earlier, around 2-6 weeks post-exposure, while NATs can detect the virus as early as 10-14 days after exposure. Knowing the window period ensures accurate testing and results.
