Hi Barbara, I very much appreciate your service for this entire world to give valuable information on HIV. Through archives, I understood window period for HIV can be extended till 1 year if coinfection of HIV and Hepatitis happens during exposure. But my doubt is, after window period of HIV(ie., 6 months), In another exposure, if a person acute hepatitis C or B or A 1. Is there any possibility, sero conversion to be changed/altered because of this NEW hepatitis acqusition? 2. Whether the person needs to wait for one more year to get comfirm result of HIV negative? 3. In my case, I had an exposure for HIV 2 years before. But, if I acute Hepatitis C or B or A anywhere in the past 3 or 6 months(Since I am getting symtoms of hepatitis now) will it alter/change already completed/finished HIV sero conversion? If I test now, will it give 100% corect result?

Please clarify my doubts and give me some peace of mind.

Thanks.

The same issue applies. If you are diagnosed with acute HCV infection, you will need further follow-up testing for HIV. However, the symptoms of hepatitis are very nonspecific, so I would not jump to any conclusions without blood testing.
