Q. Are the negative HIV tests after unprotected sex confirmatory?


Hello doctor,

My age is 26 and I had unprotected oral sex. I licked a sex worker's vagina with a lotion. I had protected vaginal sex. Performed HIV tests on 25th, 42nd, and 70th days. I also did HIV1 PCR RNA qualitative on 76th day. CMIA antibodies on 70th day. Now, we will get the result of p24 on 86th day. All my reports are negative. But, I have rashes and recently got a cold. Are my tests results conclusive? I feel each and every symptom to be related to HIV.

Welcome to icliniq.com.

HIV can never be diagnosed based on clinical symptoms. Moreover, symptoms of HIV include a generalized lymphadenopathy, weight loss of more than 10 % in short duration, long term diarrhea more than one month, etc. You have done CMIA test after 70 days that detect both antigen and antibody. It gives conclusive result after six weeks. So you may need not worry. However, the guideline says that you should repeat your HIV test after three months of exposure and that too after 85 to 90 days of exposure.
