My last possible exposure was 6years back. I have no symptoms of Hiv. But after 6years I have done a 4th generation CMIA antigen and antibody test which is non reactive. I have done HIV1 RT pcr and HIV 2 pcr as well.. Both came target not detected. But in the hiv 2 pcr test it was written that the test cannot detect if there are less than 100 copies of virus in the blood. Had I been infected with hiv2 6years back would my viral load be still below 100 and be undetected?
