What is the window period for p42 antigen/ antibody dual 4th gen HIV test? And the window period for HIV RNA PCR test? When can it be conclusive?
HIV) The CDC states that the 4th Antigen and antibody test window period is 18-45 days and the NAT PCR test to be 14 - 33 days. If these tests are taken after the window periods, are they conclusive ? I am confused because some Doctors say 12 weeks?

If the CDC states that an HIV 4th gen test window period is 18 -45 days and an RNA PCR test is 14 - 33. why are doctors on Healthtap saying to re-test at 90 days? If you used those tests at six weeks for the 4th gen test at the RNA at five weeks?
