Please advise me for accuracy of test and risk level

[jasonwing]

Dear Doctor,

My possible exposures which are multiple virginal sexes (no oral sexes) with one woman who is also low risk happens before 31 March 2008. An HIV Antigen and Antibody test was performed on 26 September 2008 (Abbott Architect HIV Ag/Ab Combo assay) in Sydney which was negative. Therefore between exposure and test there was at least 25 weeks.
Is this test 100% conclusive? I notice that CDC recommend 6 months window period. Is that 6 calender months or 24 weeks?

Also, is there any risk of getting HIV by dried blood? I remember just now I sat on a toilet seat in my home and I discovered tiny amount of dried blood (possibly others menstruation blood) on the front side of the toilet seat. I remember I haven't touch it nor my penis contacted the dried blood. Let say the blood come out from HIV+ person, is there any risk if my penis contacted the dried blood?

Thank you for reading and answering my questions.

Regards,
Jasonwing

They are being ultraconservative and relying on outdated information.

I did answer this same question in my original reply - which I have repeated here for you:-

"You are HIV negative. The test you have had is conclusive.

The CDC does not recommend testing at 6 months as a routine - this is false. In fact the CDC states that the majority of people will have formed antibodies by 25 days post exposure suggesting that for the majority a modern third generation HIV 1 and 2 antibody test will be appropriate. In your case you had a 4th generation combined antibody / antigen test which is superior and was negative.

There is no risk to you at all of contracting HIV from the toilet seat.

You are fine and there is certainly no need to test again in respect of this episode"

best regards, Sean

I am very sorry doctor. Recently I had been stressed again about my test result. I want to ask that is the length of window period related to the generation of test? If so, why are some official source (like a university in Hong Kong, or some doctors on youtube) still recommend 6 months window period?
