Hello, and thanks a lot for your question to the AIDS Vancouver Helpline.
It seems that you are looking for some information about a DUO test you had after an encounter with a sex worker. We will provide some information here to answer your questions.
First off, it's great you used protection as using a condom substantially decreases the risk of HIV transmission during penetrative vaginal or anal sex. Equally, it's great to hear you've gone for testing as it is recommended to be done regularly for those sexually active.
Here is a bit of information on the test you had:
|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.|
You say you "finally" got tested and it was negative, so we're assuming this was at least 12 weeks after the encounter. This test is considered conclusive 12 weeks after the exposure. It does test for both strains, so the test you had is indicating your status at this time conclusively (provided it's been at least 12 weeks).
Thanks a lot for your question to the AIDS Vancouver Helpline.
