I recently took an HIV RNA PCR test 90 days after exposure, and the results were negative. Can I consider this as a conclusive result? Is there any chance that the result could be wrong at this stage or due to the diagnostic centre while reporting? Please help me.

Negative HIV RNA PCR after 90 days is reliable. Certified labs give consistent results. Differences between good labs are minimal. Repeat test if lab credibility is uncertain. Talking to your doctor eases anxiety.
