Can HCV co-infection affect the accuracy of HIV rapid test results? If HIV and HCV antibodies tests are negative at 5 months, are HIV results accurate

Can HCV co-infection affect the accuracy of HIV rapid test results? If HIV and HCV antibodies tests are negative at 5 months, are HIV results accurate

It shouldn't: Antibody tests are specific for the antibodies being tested for, so hcv antibodies shouldn't have an effect on HIV antibody tests.

That's because people who aren't infected can have false positive RNA tests, and people who are positive can have false negative RNA test. ...Read more

Have only protected sex until both partners assuredly negative, and monogamous. ...Read more

The RNA test is effective around 10 days after infection but seroconversion to antibodies may take 3 months. ...Read more
