Potential HIV exposure 3/5 - I performed oral sex and swallowed his semen, didn't know his status. I took a RNA PCR test on 3/17, RNA test on 3/27, and 4th gen AgAb test on 4/19: all -ve. Conclusive even with 1 day still in 45-day window period?
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?
After windows period of 6 month which test is better to definitely rule out HIV? HIV 4th Gen test or HIV RNA PCR?
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?
