After 10 weeks (70 days) of unprotected sex with a sex worker, I took a 4th generation HIV assay test at SRL Lab, and the result was non reactive. How safe am I from HIV after 90 days? Is there any chance that the HIV test could become positive after 90 days? Can the SRL Lab report at 70 days be considered reliable? I have attached the report for reference.

A 4th gen HIV test at 70 days is highly reliable. A test after 90 days is conclusive. You are likely safe.

Answered by Apollo Doctors

Hello Doctor, I had sex with a sex worker 35 days ago. I have had symptoms for the past month, such as nail discoloration, throat dryness for three weeks, cold, constant sneezing, and penis burning sensation. Is it HIV? I tested with an antibody test today, after 5 weeks of exposure, and it was non-reactive. Please advise how accurate the antibody test is after 5 weeks?
