Then what is really the purpose of the PCR Rna for? I am not sure
PCR-DNA Tests
Neither the Abbott RealTime nor the Roche COBAS AmpliPrep/COBAS TaqMan HIV-1 assay is intended to be used as a donor screening test for HIV-1 or as a diagnostic test to confirm the presence of HIV-1 infection.

Hi thanks for your reply i have had a 4th gen and it was negative but my fear is that this could be a false negative because i have had this for a possible 15years and did'nt know until i started to show my unexplained symptoms, so that's why i have asked about the PCR at late stage. Many thanks in Advance Mikey..
Have a simple antibody test. Very accurate, especially if your exposure was so long ago.
Thanks Howard Im really grateful for your reply, I have been trying to get a answer for this so thank you very much, so a PCR RNA OR DNA will always detect the virus at late stage, the reason for me asking this question is that i have been takeing symptoms of what pointed to late hiv my last possible exsposer was 15years ago, I did'nt really know much about hiv until i started to look for what could be causeing my symptoms, so if your a 100% about this Howard then that would put my mind at rest. Many thanks again and look foward to your reply...
Late stage HIV always has poz PCR for RNA or DNA. Also always elisa antibody poz.
