hi doctor, very happy to see u again in this forum.thank u for enlightening me with so many real updated knowledge in this field until now.i still got some doubts to be clarified. i followed myself with HIV antibody tests untill 18 months to make sure that i am not infected after the incident.(receiving oral sex-blow job- from a girl who is antibody negative at the time of the incident, but i am concerned about her window period) then again considering the possibility of late seroconversion and coinfection with HCV. i did only one antibody anti-HCV test at 18 month mark. all these antibody tests came negative only. but,as doctors we cant stop thinking too much about the disease. is there any need for molecular techniques like PCR for HIV and hepatitis C to be performed to rule out even the minute and remote possibilities at this stage.. again i am scared of that molecular diagnosis PCR s getting false positives. so please give positive reinforcement to my negative status at 18 month mark,with your brilliant knowledge and experience in this field.because it will give me strenght of mind to forget this episode and move along with my new marriage relationship.
Response from Dr. McGowan
I cannot claim Brilliant Knowledge, but I am very reassured by a negative test for both HIV and HCV at 18 months. This is well beyond the recommendations for testing. Even if the young lady was "sero-converting" the test would be positive by now. There would be no reason to do the PCR as you have no syndrome of HIV seroconversion and you are negative well beyond the window period, the risk would be (as you point out) for a false positive low-level result which wuold just fuel further anxiety. Congratulations on your marriage...have a happy and health long life!
