good evening doctors. i recently had an elisa 4th generation test 40 days after a protected vaginal sex exposure. it was negative but i am still anxious.. how reliable is the test at 40 days, or should it be done at around 28 days when the p24 antigen is at its peak. many thanks
Thank you very much for your post.
Your negative HIV Duo test performed at 40 days is final and fully conclusive. There is no need for you to have any further tests. The p24 antigen remains detectable from 14 days up to at least 6 months after the initial infection.
