Hello. I am just writing to see if I understand the situation correctly. 5 weeks ago I had receptive anal intercourse with a person of unknown HIV status. The condom unfortunately broke, although he did not ejaculate. Within 48 hours I started a 28 day course of PEP, to err on the side of caution. At this time all tests (4th generation HIV test) came back negative. I self tested at 22 days and 29 days using Biosure home test kits, with each of these results being negative. Am I correct in my assumption that at 29/30 days the home test would have been around 90% accurate? I will be testing again at 6 weeks, and then will have follow up blood tests in 3 months as part of my regular STI screening, however I would just like to put my mind as much at rest as possible at this point.

Thank you!
