The tests commonly used to detect HIV infection actually look for antibodies produced by your body to fight HIV. Most people will develop detectable antibodies within 3 months after infection, the average being 25 days. In rare cases, it can take up to 6 months.

The CDC National AIDS Hotline can provide more information and referrals to testing sites in your area. The Hotline numbers are 1-800-342-2437 (English), 1-800-344-7432 (Spanish), or 1-800-243-7889 (TTY).
