Hi, I have questions about 4TH gen/duo/combo HIV test.
1) When you say the window period is 28 days, does this mean it's conclusive if the test is done ON the 28th day post exposure and beyond? or ONLY if done beyond/after 28 days?
2) Day 0 is considered the day of the exposure right?
3) Why some sites state that DUO test picks up 95% of infections at 4 weeks and 5% of people may take up to 3 months? Is late seroconversion a myth? or is this a legal thing only?
4) what about HIV-2? I know the p24 antigen is for HIV 1 , but is the 28 days window period of the DUO also for HIV 2?
5) My exposure was on 29th september at 14:40/2:40 PM. If I test on 29th october with duo, would that be conclusive?
I would really appreciate your reply because I want to test for peace of mind cause I had unprotected vaginal sex with a girl and she claims she is negative but only testing would give me relief. But also I need answers for this questions so I can feel good about the DUO test i'm planing to do.
