What Are Negative And Positive Results On A Hiv Rna Pcr
Hiv DNA PCR dectected on 4/08/13 and antibody negative.Still now 6/3/13 8 weeks later still show HIV anitbody negative. What are your thoughts? Is the PCR a false positive?
Not necessarily: Is it really the dna or the RNA pcr? The dna qualitative pcr is the most sensitive test and may become positive months before antibody is detected. The quantitative RNA pcr that is used for monitoring also becomes positive early. Antibodies may not develop until 3 months from the infection. So, they may still develop. If you have not seen a HIV physician and are not on art, see one asap. ...Read moreSee 1 more doctor answer

It shouldn't: Antibody tests are specific for the antibodies being tested for, so hcv antibodies shouldn't have an effect on HIV antibody tests. If you've tested negative at 5 months, i don't see why those results wouldn't be accurate, but if you want to be sure, you can always wait another 4-6 months and have the HIV test repeated. ...Read more

Oraquick: accurate, but as for every test there is limitation, a positive test means that an antibody against HIV is detected; However more test is needed to confirm it, a negative test does not rule HIV , specially if the test is performed during the window period of HIV detection ( window period: first 6 weeks after HIV infection, when there is not enough antibody is produced for the test to detect it) ...Read more
