Sir i have taken three 4th gen
hiv tests (ECLIA, CMIA and ELFA) besides two rapid card HIV antibody tests and One HIV RNA Qualitative test for a possible exposure 10-11 years ago, results of all tests being negative. Should these tests be conclusive and reliable enough for such an old exposure because i read somewhere that antibodies get low or undetectable in later stages of HIV, would it mean that these all tests could be false negatives or do i require any further tests?
