hiv test at 8 weeks

[wrxtc]

Hi there,
I am wanting your opinion on my situation:
I had unprotected anal sex about twice where i was the bottom, with my partner at the time, he re assured me that he had recently been tested and everything was clear.
But you can't trust anyone these days!! It really freaked me out the very little he knew about hiv and how its spread so I made him do a home hiv rapid test that has supposedly 99% accuracy, at after we had been together for like 14 weeks it was negative my partner had no other sexual partners at this time and neither did I.
After ending the relationship i got tested after 2,4,8 weeks after the last exposure which were all negative, Do i need to re test at 12-13 weeks?
Does it look promising for me that I will be hiv negative??.
thankyou

Just calculate the odds.  For you to have HIV, several very unlikely possibilities all have to turn up the wrong way.  Chance your partner was infected, despite his assertion he was not?  Say 1%.  Chance that his HIV test missed it, if he was infected?  I'll accept your 1% figure.  Chance you got infected from 2 episodes of unprotected receptive anal sex?  Also 1%.  (It's about 1 in 200 per episode.)  Chance you you have HIV despite your negative tests?  Let's say 1%, although it is probably lower.

The odds you have HIV calculate as 0.01 x 0.01 x 0.01 x 0.01 = 0.00000001.  That's one chance in 100 million.  The real risk is lower, because I used higher-than-probable estimates for the calculation.

Bottom line (pun not really intended, but sort of cute anyway):  This is equivalent to zero; you cannot be infected as a result of that exposure.

I disagree that "you can't trust anyone these days".  It probably is uncommon for HIV infected persons to lie outright and claim not to be infected.
