PCR Test

by F_ISH, Jul 23, 2008 12:35PM
I had unprotected oral sex with a man approximately 4 and a half weeks ago.  He did not ejaculate in my mouth, is adamant about safe sex (with the exception of protected oral sex), and had tested negative several months previously.  I have recently become ill and just as a precaution, my doctor is giving me an HIV test, among many other tests.  

He has decided to give me a PCR test.  I know how the test works (definitely one situation where being a biology major comes in handy), but I was wondering how accurate it is.  Does anyone know what the rate of false positives is?  Is a negative test result conclusive, or should I follow it up with an ELISA?

Thanks for the information.  Hopefully it comes back negative!

You shouldn't even be worried about this enough to have an HIV test.  Your risk is 0 and if you do happen to have HIV, it isn't from that incident you described.

Thanks for the comment.  My doctor just wants to be sure.  I have had no other incidents that would cause HIV infection since I have last been tested, so hopefully I'll be hearing some good news on Friday.
