Dear doctor, after ready views and concern about people i decided to take hiv/aids elissa test today morning which came negative,should i consider this test to be 100 percent accurate, the nurse said something about window period antigens are ok and they didn't find any hiv, so if a person has slept with somebody who has aids can the test still detect the aids virus after 2 or 3 years even when a person is close enough to die with aids do they still produce antibodies?my friend has yellow discharge everytime and has enlarged lymp nodes near anus ,itchy skin and enlarged tonsils awaiting your reply
