Likely negative: There is typically a "window" of 3-6 months after exposure where you could be HIV positive but test negative. Since you didn't get your testing until well after that, i'd say the confirmatory tests (western blot, ifa) are what you should go by. The elisa is very sensitive and can have false positives- that's why we rely on the confirmatory tests. I would consider your status to be negative. ...Read more

Complicated: Although these tests are very sensitive there are false positive results because of the potential presence of other benign species of neisseria. If you had to compare the two it would be without much relevant data. Bacterial culture will provide both a definitive diagnosis and allow determination of antibiotic sensitivities. ...Read more

Lab Error: I would chalk this up to lab error, but in my patients we do not leave it there. There is a much better and more valid test to be done called a western blot test for herpes. This definitive test should have already been offered to you so that you can know for a fact whether you have herpes or not. ...Read more

However, if you had a negative rapid test, testing is generally considered complete unless you are having other signs or symptoms of an acute HIV infection. ...Read more

Multiple causes: On the average, 0.2 percent of elisa tests give a false positive HIV test result that are then proven incorrect by a western blot test. Autoimmune diseases, recent vaccinations, multiple pregnancies or prior infections with hepatitis b, malaria or tuberculosis can stimulate the production of antibodies that cross create with hiv, thus producing a false positive HIV test. ...Read more

Be grateful, man!: You've been obsessing about this too long. Sit down and talk with your physician about fears. If you'll forgive my frankness, talk with him/her and some wise adults (maybe even dad) about your emerging sexuality and how you've explored. By your age, we've all made mistakes. Embrace being a man, decide how you want love to be for you, and cherish adult love while resolving to be safe ; kind. ...Read more
