Should Combi E170 Test Be Done After A Specific Period Of Time For Accurate Result?
Hi Doctor, I had a combi E170 test 2 months after exposure (exactly 11 weeks). And the result was negative 0.219. I have a concern that whether I need to conduct another test 5 or 06 months after exposure? I m at 5th month after exposure. Thanks and Regards,

Hi there,
I understand your concern,
Combi E170 is approximately 97% sensitive at 11 weeks, but in 3% cases it may take up to 6 months for antibodies to develops, so just to rule out any remote possibility of HIV I would advise you a repeat test at 6 months and if it is negative then just relax and not to forget using barrier method of contraception in future.
Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.
Wishing you good health.
