I had a exposure 145 days ago (almost 5 months) I had a hiv ab/ag 4th generation test at 13 weeks and number of hiv test past 13 weeks recent one 20 weeks oraquick (negative).I am wondering do I need to test at six months and the possibilty of a false negative hiv test at 145 days ?
If you truly had a risk (unprotected vaginal or anal sex), then your 13 week result is conclusive. You do not need ANY further testing, there is NO need to test past 3 months.
You do not have HIV.
