PCR tests
      #20884 - 08/15/01 04:13 PM

I read that PCR tests are not reliable enough to test for HIV presence, and that they can show false positive results. However my doctor ordered a PCR at 2 months. It came back negative and he said it was conclusive. Is that good enough? I had no other tests done after that.

They shouldnt be used by themselves to rule out infection. Fallow up with an Elisa, but from the sound of it you dont have anything to worry about!

If PCR test cannot be used by itself to determine infection, how could they say that this test is 99.997% accutate, and why did you think that it sounded like he (or she)was fine?

This is why I never changed my major from pre-med....now I understand why doctors get annoyed easily. Think about it you CAN use it, but it should not be used by itself to determine infection because IT IS NOT 100% ACCURATE!!! A standard Elisa is used in medical setting to confirm the PCR results, BUT the length of time and the timming of the PCR the chances of him being infected are next to none, BUT he needs an Elisa to confirm it. Lord people common sense. Don't read into everything you see.

True. However, the inaccuracies stem from false POSITIVES, not false negatives. Saw my GP today, he dealt with HIV a lot in the military and claims to stay current. He says a negative PCR DNA is conclusive in a suitable time frame (i.e., 28+ days from possible exposure.)
