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

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

Not entirely: If positive it needs to be confirmed. If negative, you should repeat it as some people take up to a year to make enough antibodies for a positive result. If you wish to make sure, ask your doctor for an HIV nucleic acid test which would be conclusive at 4 months after exposure. ...Read more

Hiv pcr plasma test at 8 weeks and antibodytest at 6 week post exposure negative. How accurate, reliable? can they detect if coinfection with hepatit
Around 50%: Roughly half of newly infected people would have a positive duo test at 10 days. If at truly high risk, like unprotected sex with a known infected partner, ask about an RNA test for the virus. However, heterosexually acquired HIV remains quite rare in the UK. If at lower risk, have another duo test at 28 days, which will be conclusive. Or get expert advice at an NHS GUM clinic. Good luck! ...Read more

How conclusive is 4 th generation HIV testing after 4 wks exposure when negative and what are chances of positive in 3 mt window period?
Repeated questions: It is offensive and an abuse of this powerful application to keep asking questions that have been answered already. Here is my answer as an ?HI.v expert who tests fife to ten patients daily. At four weeks I would never offer you the fourth generation or other HIV antibody test. I think it malpractice to do so. This early you would get the 100% accurate RNA test. ...Read more
