Hi there, and thanks for contacting the AIDS Vancouver Helpline for your HIV/AIDS related health information. It seems you have a question about testing. We're happy to answer your question for you.

If you're concerned about an exposure occurring in April of this year, a test anytime after July would be conclusive of your status, so you can go for a test any time.

Thanks for contacting the AIDS Vancouver Helpline with your question, we hope it has been answered fully.

Test Name Method Window Period Conditions
4th Generation EIA Blood test that looks for antibodies AND p24 protein antigens. Commonly referred to as the "combination," "combo" or "DUO" test. P24 protein is detectable immediately after infection but only for the first few weeks. The antibody (ab) test has a window period of 4-12 weeks post exposure. This test is widely available in North America. Most HIV specialists consider this test to be conclusive at 6 weeks but official HIV testing guidelines still recommend re-testing at 12 weeks for conclusive results. Conclusive at 3 months post exposure. |
