PCR or RNA Jul 8, 1999 Dr. Can you tell me the difference between a DNA PCR test and an RNA test that tests for copies of the virus. Which test would be more accurate at detecting infection? Are they both very accurate? I know the antibody test is the gold standard but if one were to get an additional test after the 6 month waiting period which would be more accurate? Thanks. |

 both test for presence of the virus, but in different forms. RNA looks for virus particles in plasma. DNA PCR looks for HIV that has been incorporated into cells. You dont need either after 6 months, if antibody tests are negative. MH | ||||||||
