###Human: Is it possible to have symptoms of STD or HIV after three months of exposure? ###Assistant: Hi. Please say whether the throat pain got resolved with medications. If you have it, then it is unlikely to be a cause due to HIV infection. Secondly, the home kit for HIV has a low sensitivity and low specificity. So, it is inconclusive. ELISA (enzyme-linked immunosorbent assay) is a standard test advisable for HIV testing. Since it is four months, the window period for acquiring an HIV infection has overlapped, and hence, having a negative report at this point is very sure to conclude as not having HIV infection. I would suggest you get tested for ELISA now and repeat it after four weeks again or after a month. Also get a swab sampling done for your throat pain and consult a physician.
