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.

I tested myself for HIV 50 days after exposure using a CMIA Duo test, and the result came back non reactive. Can I consider this result conclusive?

I had unprotected sex with a sex worker. After 28 days, I took an HIV RNA PCR test, which came back as not detected. However, after 80 days, I took a Western blot test, and the result was positive.

What does exposure mean? Which period counts as the exposure period? Also, what is the window period, and is three months sufficient for a conclusive HIV test result?
