Before 74 days I had an unprotected sex and gone through many test. My last test was on 10th week hiv duo test which was negative. I have done pcr dna test on 8th day and not detected. I had also pcr rna test on 34 day and its not detected. Do I required western blot test or simply I will take again a duo test on 12th week to completely rule out from hiv or again I have to wait for 6 month to see the conclusive. I am so scared and Dr. are telling not to worry but still need some elaborate answer to rule out my mind for hiv free. Please help. Also had 29th day hiv duo and its negative. And index range was o.49 on 29th day and 0.28 on 67th day. Why this changes slso can any body assist.
