Can a blood test be determined if a man has genital herpes?

Yes and no....: A blood test can tell whether someone is infected with herpes simplex virus type 1 (HSV1) and/or HSV2. It doesn't tell if genital or oral; that requires symptoms and/or testing of an outbreak for the virus. Most HSV1 is oral, some genital; almost all HSV2 is genital. The tests aren't perfect, but if you have symptoms that suggest GH or an infected partner, testing can be helpful.

If you get tested for HSV, be sure to ask only for immunoglobulin g (IgG) testing only. Do not have an IgM test, even though it is routinely offered by many labs. The HSV IgM tests are notoriously unreliable. The results are never useful, and experts in herpes, STDs, and infectious diseases never recomomend or rely on them.
