1) Same as for HIV-1, to my knowledge.
2) Yes.

Doc,
I asked the testing lab if the test checked for HIV2 and they said yes it did. Question on the HIV2 thing again:
1. what is known about the window period for HIV2?
2. would it come up in a test at 8 weeks?
Thank you for your help.
Yes. Oral sex is virtually zero risk for HIV transmission.

Yes, protected vaginal sex, but "unprotected" oral sex. Are my chances pretty much zero to have HIV from the oral sex to at this point?
Wow! All that testing for a single episode of protected vaginal sex? The chance you acquired HIV is almost zero, certainly less than one in a million. (OK, maybe as "high" as 1 in 100,000 if your partner happened to have HIV, which she probably didn't.)
1) Search the forum for "time to positive HIV test" for giant amounts of reading on this topic. Virtually everyone is positive by 3 months, but with modern tests most infected people develop positive results by 4 weeks and it probably approaches 95-99% by 6-8 weeks. There is some debate around the specific figures, but the point it that it is not necessary to wait 3 months to get useful information, and I believe it is wrong to counsel people that they need to wait 3 months before first being tested. Anyway, with a negative result at 8 weeks, the chance your test will turn positive by 3 months probably is less than the chance you'll be struck by lightning--i.e., virtually zero.
2) Last I checked, roughly half the HIV tests being routinely used in the United States were dual HIV-1/2 tests. If your test says HIV-1 only, I'm sure that's what it was.
3) HIV-2 is extraordinarily rare in the US. I'm not sure that even one sexual transmission has been documented; most (all?) of the rare cases so far were acquired in other countries. So the chance you have HIV-2 is zero, for practical purposes.
4) Read the innumerable other threads on "time to positive HIV test". For most people in your circumstance, in which there is no medical indication for testing, only the reassurance, stress-reduction benefit, I recommend a single test at 6-8 weeks; or, if not too nervous and able to wait 3 months, a single test at that time.
Good luck-- HHH, MD
