I had an HIV test at 86 days post exposure which came back negative. I am a bit confused about guidelines, some of which say that 3 months (90 days) is conclusive and others say that 12 weeks (84 days) is conclusive

Which is it, and can I take the result of my test at 86 days to be conclusive?

Many thanks in advance.

Response from Mr. Cordova

Hi there,

As a rule of thumb, it is 90 days. However, I would not expect your result to change between 86 and 90 days. No further testing is required.

In health,


am i infected
Can I get infected if I drink water that has HIV infected blood in it?
