P24 test Accuracy - too soon?
Doctor,

I took a P24 antigen HIV test (4th generation) 25 days after exposure (3.5 weeks), which turned out to be negative.

Can I safely say that I am probably negative for HIV? they say this test is accurate between 3-4 weeks...

thanks

Yes, MedHelp's expert HIV doctors all agree that a 4th generation test taken at that time rules out HIV. However, this forum recommends that you have an antibody test at 3 month for confirmation. It will be negative.
