HIV infection can be detected using ELISA Test, which stands for enzyme-linked immunosorbent assays. A Western blot test is usually administered to confirm a diagnosis when an ELISA test is positive. In the event that an ELISA test is negative, but you think you may have HIV, you should be tested again within one to three months.
