How accurate is a Negative PCR DNA test for HIV at 28 days after a possible exposure? I was told this was 99% accurate for HIV diagnosis. Should I have waited longer, and should I continue with antibody tests at 3 months? Thank you.

The accuracy statement is correct. There is always the remote chance of the later establishment of infection, or the dates of possible exposure might be wrong. I would still followup with an antibody test. The current testing algorithm still recommends a 3 month and 6 month HIV antibody test. MH
