I am a heterosexual female, healthy, not on any medications and do not have any preexisting health conditions. I also do not have any symptoms. I had multiple unprotected sexual encounters with a male for about a month and a half. Our last encounter was November 27th, 2015. I am not aware of the partners status in terms of HIV (or any other STDs). I did blood work to be tested for all STD's, including HIV using the ABBOTT architect DUO. I also had a pap smear done. My doctor said everything is negative and everything looked fine. At 8 weeks i had another DUO HIV test, which was also negative. I am from Ontario, Canada and have talked to an HIV hotline. They indicated that 13 weeks is the only way to get a conclusive result for HIV. Is this correct? Should i test again for HIV? Also, should i retest for any other STDs at the 12 week mark? I'm not sure how conclusive the tests are for other STDs (ex. syphillis, HPV, etc). I am getting somewhat anxious over this issue because i have gotten numerous responses in terms of window periods. My doctor for example told me the window period for HIV is 6 months and it would not show up even if i had it. 

You can relax. I'm afraid you have found a number of unreliable resources, and it's disappointing that the HIV Hotline is also behind the times. The fact is that the duo test, which is based on detection of both HIV itself (the virus's p24 antigen) and the immune response to it (antibody to HIV) is conclusive any time 4 weeks or more after the last possible exposure.  In addition, the statistical likelihood your partner had HIV is very low, probably under one chance in a thousand -- or maybe as high as 1% (1 in a hundred) if he was bisexual or an injection drug user. Your own doctor appears to be even more misinformed; people used to worry about 6 month window periods with old tests not used the past 10-15 years, but no longer.

As for other STDs:  I hope you had testing (vaginal or cervical swab, or perhaps urine) for chlamydia and gonorrhea. Those are the most likely STDs you might have acquired. Those tests are conclusive from a few days after exposure. Syphilis: statistically extremely unlikley (almost as rare in this situation as HIV), but conclusive at 6 weeks or more. HPV:  no reliable test exists.  A negative pap is fine, but is not in itself a test for HIV. You'll just have to live with the knowledge that we alll get genital HPV, usuallly several infections, during our sexually active lives; and your risk is no higher on account of this particular partnership. Beyond that, I wouldn't recommend any other STD testing at all.

So all is well. If you were my patient (and even if you were someone close to me personally) I would say to stop further testing and go no with your life with no further worries about this past relationship.

I hope this has been helpful. Best wishes to you--  HHH, MD

Thanks for the thanks. I'm glad to have helped.

That said, if you insist on hepatitis testing, it should be 6 weeks for hep B and 12 weeks for hep C.

I forgot to add, i tested negative for chlamidiya and gonorrhoea. 

I cannot say the risk you acquired genital herpes is zero from the relationship described, but it's very low. It is true that genital HSV often is asymptomatic, but that's often because mild symptoms go unnoticed. People who are especially concerned and on the lookout for symptoms are more likely to not miss them. Accordingly, absence of S&S in your situation is quite reassuring. Testing for HSV in this sort of situation is controversial, mostly because the HSV blood tests are not perfect. They not infrequently give borderline results that require still more testing to sort out the truth (and a lot of anxiety during that process). Also, nearly half of all adults have positive IgG results for HSV1, usually from oral infection and often without symptoms, with usually with no way to know with certainty whether the infection is oral or genital. If you do it, for sure have an IgG test only, not IgM; and I would recommend waiting until 12 weeks after your last sexual exposure in that relationship.
