Is it true that HIV is detected by the test 90 days after you got infected?
If this is the case I don't see the point of getting tested. I need to know if I'm HIV free now, not if I was HIV free 3 months ago.

ummm, i guess i don't understand the question. yes it is a 90 day wait period from your last possible exposure recomended by the CDC. it takes that long for the anti-bodies to show up. it is just a matter of biology, not to make you mad. your last sentence is what is throwing me for a loop. when you get the test it DOES tell you if you are HIV free now based off of an exposure(s) 90 days ago, not the other way around. hope this helps.

I hope I am understanding your question but a test you take today will not show what your status was 90 days ago. You need to wait 90 days from exposure to have enough time for the antibodies to show. Anytime after 90 days is going to give you an accurate result of your status at the time you take the test. :p

Yes, you did understand my question, thanks for the replies.
So there is a 90 days period since you get infected until the virus shows up in the test then. This means that if I get tested today and it comes negative I'm not completely sure that I'm not infected, I should wait 90 days and get tested again (actually 90 days from exposure like you said).
This also means that I cannot really trust that the person I'm having sex with isn't infected just because her test came up negative, unless she haven't expose herself to the virus in the last 3 months. But how can you be completely sure about that?
What bothers me (and I know this is nobody's fault) is that the test is not completely accurate. I know it is accurate but it is not updated, that's what doesn't make it "completely" accurate.

Yes, you have to wait 90 days from exposure to be completely sure. And about the test being accurate..it is accurate. I mean, nothing is 100% but it's like 99%. That to me is accurate. I'm no dr. but when you get any type of test done they are all like that...there is a tiny margin for error. I would definately trust a HIV test result. The only time they re-test an HIV result is when it comes back Pos. If it comes back Neg...then it's Neg. I hope this helps.

Peter,

You are corrrect: you CANNOT be sure that the person that you are having sex with is HIV free today even if he or she tested negative yesterday AND tomorrow or last week AND next week!
That's why safe sex procedures are important.
