accuracy HIV test 82days

3months ago, I was in holidays in Cuba and had sex with a prostitute.
We French kissed and bite each other lips quiet a lot. Then she performed unprotected oral sex on me while I was fingering her. We had protected vaginalsex.
The next day( in the afternoon), I noticed a small cut on one of my finger that I used. I can not say if that cut was fresh or from before that event.

Got tested in the UK at 82 days (don t know which kind of test they use in the NHS sex health centre in leeds), all my results are negative (HIV, std's, syphilis...)
I know it would have been better to wait 90 days or at least 84 but I had a appointment for a boost shot for something else so I got tested in the same time.
Can I assume the negative HIV test at 82 days is accurate?
Should I get tested again?
Thank you Doctor

Good Morning and thanks for the post,

You were not at risk of HIV from the activities described, even assuming the girl was HIV positive, which is actually unlikely.

Kissing, fingering and being sucked does not convery an HIV risk.

It is very very likely that the HIV test used was a 4th generation HIV test and so will have been very good for that time.

You do not need to test again.

best wishes, Sean

Thank you very much doctor
