Still worried I see. As I told you before, yoir risk for any STD, including HIV is quite low, thus your test results do not suprise me. Your results inidcate that you do not have HIV and should be believed. That said, in general we do not recommend HIV PCR testing for diagnosis is HIV infection for several reasons. While the PCR is likely to become positive more quickly than other antibody detection tests (i.e. usual blood tests), at the present time the blood tests are becoming more and more sensitive and detecting infection earlier and earlier so that the time difference in detection between PCR test and antibody detection tests is becoming smaller and smaller and at present is, in general only a week or two. In addition the time course over which the PCR tests become positive is less well described than for the blood tests and, as a result, it is difficult to make a definitive statement on what a negative PCR test means at any time within a few weeks of exposure to a HIV infected or possibly infected partner. PCR tests are also more expensive than regular antibody tests. Finally and most importantly, the false positive rate for PCR tests (i.e. a positive result in persons who do not have HIV) is higher than for blood tests. Each of this on this Forum have seen a number of people who were worried needlessly because of false positive tests. For all of these reasons, we rarely recommend testing for HIV diagnosis using PCR.
My advice (again) would be to relax. I see no need for further testing (of any sort). EWH
Thanks again Dr.
Just to close the book (but not meant for you to repeat your opinion). I had a broad test of Syphillis, Herpes 1 and 2, Hepititus, ect.. done 2 weeks after last sexual encounter. All came back negative. Was that enough time to build a conclusive testing result for the above STD's?
Thanks and best wishes/blessings...
No, two weeks is not sufficient time for tests to uniformly become positive. In terms of the time for tests to be definitively negative (tests become positive at varying times) 4-6 weeks would be definitive for syphilis, 3 months would be definitive for hepatitis viruses and we do not recommend blood test to diagnose herpes however we do know that tests can become positive for up to 6 months following acquisition of infection.
