81 days accuracy ( Teak Or Lizzie Lou)

( SORRY FOR REPOSTING BUT NOONE ASNWERED MY LAST ONE) (LOOKING FOR EXPERT TO ASNWER) From reading I know tests aren't conclusive til 3 months (90 days). However, I took a test yesterday at about 81 days post risky exposure and it came back negative. I was wondering percentage wise, how accurate is a rapid hiv test at 81 days? If you could give me a percent I would greatly appreciate it. Thanks

Well you were answered. A test will not change in 9 days. You can take it as conclusive. The percentage is 99.99999%.

The reason the 3 months is conclusive is because that is what was accepted and passed by the FDA. But some days are not going to make a different. In reality 8 weeks is considered conclusive by the Dr's on this site based on experience.

I took a test exactly at  81 days past exposure to a hiv positive person. Can I consider myself negative with my results being negative at 81 days after?

It was a number that they were confortable with after years of testing. The manufactures had to prove that 3 months was a conclusive time frame. But the senestivity of the tests are very good so while 3 months is conclusive and that is what we go by just about everyone will test positive by 8 weeks.
