I had a risk exposure with a unknon status CSW 3 months ago. After the 3 months I had done a HIV DUO Quick (p24 & abc) test in a private lab. The test result came out negetive. . HIV DUO Quick (p24 abc) test is a acqurate test at 3 months? But I did not done HIV 1&2 antibody ELISA Test. Need HIV 1&2 Anitbody (Elisa) to conclusive? Still I have skin rash, dry cough, white tongue and night sweat.
