What kind of unprotected sex did you have?
So, I'm not anxiousnomore but will try to answer. You've tested negative at 28, 33 and 57 days post exposure? All negative? That's good news. That means you are negative! On the question regarding 28 days and the separate tests, those two tests do look for the same thing as the duo and both were negative. The two tests combined give you the same information as the Duo so you should consider it the same as a negative Duo result. To make sure those negatives were accurate, you followed up with further testing almost 8 weeks out and still negative. You should relax and move past this.

You are conclusively negative. You do not have HIV. The level of risk has nothing to do with the timing of the test. Three of us have now told you your test is conclusive - time to move on from this event.
