A member asked:
So if i take a hiv 4 generation combo test at 4 months after exposure (unprotected vaginal sex) will it miss the p24 antigen at this point and if so will pick up the antibodies. is it possible both will be absent at 4 months. why 6 months wait?
A doctor has provided 1 answer
4th gen neg = neg: 4th generation tests are extremely accurate. “Official” recommendation is to wait 6 months (based on older, less sensitive tests - will probably update eventually). If 4th generation is negative a 4 months, you are negative and do not have HIV.

I took a 4th gen HIV duo test 114 days after unprotected sex. Is this conclusive? do i need 2 negative results for it to be conclusive. The antigen seems to only be in the body for up to 50 days. What if i didnt have detectable antibodies by 114 days?
I do unprotected vaginal sex 4 months ago... I do hiv duo test at 28 days and antibody test at 3 months which is also negative? What is accuracy?
Have unprotected vaginal sex 2 months ago. done HIV Pcr after 37 days and combi test after 51 days and antibody test after 70 days, all came negative.
I got a 4th generation hiv test at 24 weeks and it was non-reactive. Is the 24 weeks considered 6 months and is it conclusive ? Any chances the test would miss either antibodies or p24 antigens? I want to move on from this and need closure on this?
Hi all thanks in advance! Do antibody and antigen hiv tests detect all strains? Including type O and the new VB? Tested negaafter window period can the combo miss an infection? So many different answers to this on academic sites?
