Q and A


Is a negative test after 3 months accurate?

Dear Sir,
I had sex with massage girl on June 08, 2007, she removed the condom from my penis 3-5 minutes before finishing the sex (vaginal sex).
Five weeks (37 days) after the exposure, I got HIV test and the result was negative. 91 days after exposure I got HIV test again for confirmation, the result is negative. My questions are:
1. Does it mean that I am really HIV negative?
2. Should I get HIV test again next December 2007 (6 months after exposure)?


To question #1: Unless you had another exposure risk during the 91 days period, then yes, the test shows that you are HIV-negative.

To question #2: In very rare cases it takes more than 40 days for the body to develop antibodies to HIV that can be picked up by the test. That is why it is a good idea to test again 3 months after the possible exposure, even though the chances of a positive result then are almost negligible.

    Good morning. I had unprotected oral sex with a male (circumsized) whose HIV status i am unaware of. I am a female and he ejaculated in my mouth. I spitted it out quickly but i am not sure whether i could have swallowed some semen or not. we did not have sex, only oral sex. I did HIV type 1 and 2 tests after 1 month and 2 month including all STDs tests and i tested Non-Reactive for the HIV and negative for all STD. However it is only now (after the 2 months of exposure) that i am having some swollen lymph nodes in my armpits with a burning sensation. Is it possible that i am having some symptoms now? what are the odds of getting HIV from such an incident?
