Hiv Rna Test Accuracy
HIV is also known as HIV/AIDS. Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more
Is my 8 wks 2 day PCR RNA + 4th Gen test negative conclusive for HIV infection after vaginal exp? Or do i need to test after 12 wks or it has to be after 13 wks? Pls answer, Thanks for any response
Relax, Mike: I understand that you're a man worried about HIV after an unprotected episode of intercourse with a woman. The nucleic acid tests are almost always positive by this time -- we can't even estimate the frequency of their turning positive only at 12 weeks because history isn't always accurate. Retest only if you or someone close to you is obsessed over it. Love wisely and well from now on. Cheers. ...Read more
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?
See below: Please consult this site for a detailed answer. Nucleic acid tests are conclusive about a month after acquiring infection. http://www.sfaf.org/hiv-info/testing/hiv-test-window-periods.html ...Read more
Not for diagnosis: It's very useful for monitoring the response to hiv, and it's accurate to diagnose or rule out acute HIV infection in someone with symptoms, but for simply diagnosing HIV infection, the HIV serology (antibody test) is better. 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
Uncertain...: There has been little or no research on the extent to which PEP, if unsuccessful in preventing HIV, delays diagnostic test conversion. Probably a negative RNA test 18 days after completing PEP is close to 100% reliable, but nobody knows for sure. Some experts continue testing for 3-6 months after PEP. That's one of its disadvantages: prolongation of the period of uncertainty and anxiety. ...Read more
What is the accuracy of HIV testing (antibody and antigen) 6 weeks post PEP? I had all tests (Neg) including the pcr rna test at 22 days post pep.
HIV testing & RNA: Read the CDC updated recommendations on HIV testing. The rationale for this test being available is that HIV RNA is detectable in plasma before antibodies. A safe approach is to be tested after the eclipse period after potential exposure when no RNA nor antibodies to HIV can be detected. The RNA test is effective around 10 days after infection but seroconversion to antibodies may take 3 months. ...Read more
