Genital herpes can be detected by a blood test when you are well. Genital herpes is a sexually transmitted disease caused by herpes simplex virus (HSV) infection.HSV-2 infection can be determined by taking a blood test. It is positive for HSV-IgM during the acute infection phase, negative for HSV-IgM when it is cured, and positive for HSV-lgG antibodies. Therefore, a blood test after genital herpes is cured can still measure whether or not you have been infected. The herpes simplex virus antibody test is the basis for diagnosis and an indicator of the effectiveness of treatment. However, the standard of genital herpes cure in the clinic is not based on the blood test, but based on whether the clinical symptoms of the patient disappeared, and whether there is no recurrence after 6 months of treatment to determine. If you are suffering from genital herpes, you should consult a doctor in time, follow the doctor’s instructions for examination and treatment, do not leave it alone, and make a mistake.
