I had unprotected oral sex 7 days ago with someone who said they have a low CD4 count, so I am worried they might be HIV positive. I started PEP at around 69 to 70 hours after the incident and have been taking it for 4 days. Now, I have symptoms like intermittent fever, swollen lymph nodes, sore throat, rash, and joint pain (especially in the knees). Are these symptoms due to HIV infection or side effects of the medicine? My initial test was negative, when should I get tested again?

Symptoms likely from PEP (fatigue, rash, nausea). True acute HIV symptoms take 2 to 4 weeks. Continue PEP fully. Test at Day 28, 6 weeks, and 3 months. Avoid unsafe contact during this window. Negative tests after 3 months are conclusive.

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.

Answered by Apollo Doctors

I took an HIV RNA PCR test at a diagnostic centre after 90 days of exposure, and the result was negative. Can the HIV RNA PCR result be inaccurate depending on the diagnostic centre? Does the reliability of the result vary between centres, and how important is it that the centre is certified for HIV RNA PCR testing? Please guide me.
