Herpes Diagnosis

If you have symptoms of herpes infection, or experience any break or irregularity of the skin, contact your health care provider for a diagnosis. Your health care provider may be able to tell if you have a herpes-simplex infection simply by physical examination of the lesions, blisters, or ulcers and examination of the lymph nodes in the neck or groin. A tissue scraping or culture of the lesion can be used for examination in the laboratory to confirm the health care provider's findings. If no blisters or ulcers are present, a blood test can also be used to detect a herpes infection.

As much as 90% of people with genital herpes are unaware that they have the virus, so it is important to be diagnosed to prevent the spread of the virus.
