Hiv pcr plasma at 8 weeks, hiv antibody test at 6 weeks post possible exposure. how reliable and accurate? could it have detected if there coinfection
No evidence of HIV-1: This is good news - PCR tests are extremely sensitive, so if 'nothing' was found at 8 weeks, I'm 99.9% sure you don't have HIV. In addition, you have a second test -for HIV antibody that is also negative 6 weeks after a possible exposure. So this means you're absolutely HIV free - just remember to be 'safe' out there. Talk to your doc about the best ways to protect yourself and others. ...Read more
Test accuracy: Every test we do has a margin of error, due to both the nature of the test itself or how people behave when they collect samples, and the biologic variation between people. That said, the antibody tests for HIV perform quite well and in the setting of a suspect exposure are largely conclusive. However, the nucleic acid tests are far more specific than antibody-based tests can be. ...Read more
I had a ANA test done everything came back good beside rnp antibodies. Value 1.8 reference range 0.0-0.9. Everything else was good is this bad.
It is barely positiv: So results must be interpreted very carefully with all clinical symptoms taken into account. A test by itself is just a test. You might need a good rheumatologist ...Read more

Can HIV be dormant for 8 wks aftr unpro expo and not detect Viral Load n Combo Antigen test at 8 wks then active at 9 wks? I knw it can for antibody
Same answer as last: HIV seroconversion to detection post exposure is not definitively predictable, so this scenario can be true as stated in your question. That is why most experts recommend post exposure protocols that involve testing at baseline post-exposure, than 3 mo/6 mo/ 12 mo/ and 18 months. ...Read more

Hiv DNA PCR dectected on 4/08/13 and antibody negative.Still now 6/3/13 8 weeks later still show HIV anitbody negative. What are your thoughts? Is the PCR a false positive?
Not necessarily: Is it really the dna or the RNA pcr? The dna qualitative pcr is the most sensitive test and may become positive months before antibody is detected. The quantitative RNA pcr that is used for monitoring also becomes positive early. Antibodies may not develop until 3 months from the infection. So, they may still develop. If you have not seen a HIV physician and are not on art, see one asap. ...Read moreSee 1 more doctor answer
