Hi, I had a possible exposure around 10 years back, recently went for HIV antibody test 3 times, all 3 tests came non reactive/negative. But in my blood report WBC count is 4300, lymphocyte percentage is 21%, which is 900, is this low lymphocyte count? I heard 30-60% of lymphocytes are CD4 and below 500 CD4 count denotes HIV infection, should I be worried about my CD4 count? are my HIV results conclusive?
