If you are talking PCR-DNA tests they are not approved for diagnostic use. If you are talking PCR-RNA tests they are supplemental tests used in conjunction with antibody tests. So it doesn't matter what the PCR-RNA results are it still has to be followed up with an antibody test.
What Causes the False Positives? I understand it is not a diagnostic test and it measures the viral load in ones blood. But if the test is actually looking for the virus how does one get a false positive?
If i had a low risk situation (recieved oral sex from a sex worker who i believe was infected) and had a negative pcr rna test since i was experiencing ars symptoms. When should i take the follow up antibody test? 2 weeks after ars symptoms should be positive if they were actually ars?
Oral sex is no risk. Anymore questions start a thread dedicated just to your questions.
