Hey Doc, What about PCR??

Jun 7, 1999

First thank you for all your effort. Now here is my question, I had a possible exposure (oral sex on a Male possible pre-ejaculate exposure). I had a ultrasensitive pcr-dna qualitative done at 13 days, I also had a Elisa done at the same time. I intend to have both repeated at 4-6 weeks from exposure date. Is the Ultrasensitce pcr good enough at 4 weeks if negative or how long should I wait to get this done? I think the threshold on this test was 50copies.

THank you so much

Response from Dr. Holodniy

The PCR test at 13 days is too early to be conclusive. At 4 weeks, it should be positive in pretty much everyone who is infected. The longer you wait, the more definitive PCR and antibody tests will be. MH
