Expert Q & A Answers About when to test for HIV

Can you tell me when to test for HIV?

Hi. I want to know when to test for HIV. I ended up going home with a guy I met last night and we had sex. We didn’t use a condom and now I’m really worried...what if he had HIV? Can I get tested for HIV right away, or do I have to wait?

What is the window period for HIV testing?

I had a potential HIV exposure on a past weekend and began having symptoms that caused me concern five days later. Eight days after potential exposure, I had an HIV Early Detection test. Today the results came back negative. How confident should I be in this result? Doctors I have spoken to seem to think that even with my symptoms, the actual risk is very low. I would appreciate you sharing any information you might have in similar situations, i.e., similar timelines or anecdotal evidence. Also what is the earliest positive from HIV DNA testing known?
