An antigen/antibody test performed by a lab on blood from a vein can usually detect HIV infection 18 to 45 days after exposure. An antigen/antibody test done with blood from a finger prick takes longer to detect HIV (18 to 90 days after an exposure).

If you have symptoms of HSV type 1 or 2, your doctor can diagnose a herpes infection by looking at your skin and/or by swabbing the sores to test for evidence of the herpes virus. If you do not have obvious symptoms, a blood test can help determine whether you have an infection.

In general, it usually takes around two weeks for symptoms to appear after you have been infected with HSV type 1 or 2. 8﻿ If you do not have lesions that can be swab tested, it is a good idea to wait at least a month or two before getting an HSV-2 test after a potential exposure.

Cell culture or PCR test may give a false-negative result if the sores have begun healing or if you are recently infected. It takes several weeks for HSV antibodies to show up in the blood. A false-negative test shows you don't have the condition when in fact you do. False-positive test results are possible, too.

As with the Rapid test, most guys (about 90%) will develop enough HIV antibodies to be detected three to four weeks after infection. The big difference is that it is done with blood drawn from a vein. The blood is sent to a lab and you will have to wait up to five days for the result.

Talk with your healthcare provider about your test result and the type of test you took to understand what your result means. You could still have a current infection. The test may be negative because it typically takes 1–3 weeks after infection for your body to make antibodies.
