In brief: HIV window period

Most people develop HIV antibodies within 2-8 weeks of their infection.
The average is 25 days. 97% of people will develop detectable antibodies in the first 3 months. Rarely, it can take up to 6 months to develop antibody. If there's concern about acute hiv, a test that measures HIV RNA viral load can be done. The time between HIV infection and RNA detection is about 10 days. Talk with md.
