This forum is limited to prevention of HIV and to safe sex in general. If you believe you might have been exposed to HIV and want help to judge your risk, would like advice about HIV testing, or have questions about the effectiveness of condoms or the risks associated with specific sexual practices, this is the site for you.
IMPORTANT
No questions will be accepted on the treatment of HIV/AIDS or its complications, viral load, and similar topics. If you have questions about a specific STD other than HIV/AIDS, please visit the
STD Forum.
Questions that do not pertain to the above topics will be removed from the forum.
If you have not done so, please review
other threads in our archives for questions similar to yours and Dr. Handsfield's replies. Questions that duplicate other frequent ones, for which abundant replies exist, and that have little educational value for other forum users, will be
DELETED WITHOUT RESPONSE. YOUR PAYMENT WILL NOT BE REFUNDED. The most common examples of such questions are those about low risk exposures to HIV, such as oral sex, condom- protected intercourse hand-to-genital exposure, and nonsexual contact with possibly infected blood or body fluids as well as symptoms of early HIV infection.
Thanks for the quick reply and detailed reply. I am going to follow up with Primary Care doctor on Nov 8th to explore what can be going on. I just was curious to why you wouldnt reccomend the PCR Test? Do you think it can be used as a tool to find out within the window period if one has been infected?
Thanks for the reassurance.
The PCR test has a relatively high rate of false positive results, much higher than with the antibody tests. It's main use is to monitor viral load in people with known infection. For diagnosis in the window perriod, the test is recommended when the risk of new infection is especially high, e.g. if a person has had unprotected receptive anal sex with a known infected person. But in low risk situations, many or most positive results are false. Such persons then go through an agonizing several days thinking they have HIV when they do not. It isn't a pleasant experience. And if the test is negative, as in your case, it still doesn't prove anything; it is only partly reassuring without giving a definitive answer.
So many experts agree it is a misuse of the test in situations like yours. Admittedly, your situation is borderline, because bottomed with a high risk partner, and there might have been some doubt whether the condom remained. So although I would not have recommended you have a PCR test, some experts might disagree with me. But there would be no disagreement in the more common stories on this forum, after (say) oral sex, or sex with women at low risk for HIV.
And to repeat my closing comment above: Think how much less anxious you would be about all this if you knew your partner didn't have HIV!
