How is herpes diagnosed?
Health professionals diagnose herpes by taking your medical/sexual history, performing a clinical examination, and ordering laboratory tests. The presence of herpes virus can sometimes be determined from a swab of an active lesion (sore). A blood test (serology) can determine if you have herpes, even if you don’t have symptoms. Newer serology methods utilize highly specific technology that can determine if you have herpes type-1 or type-2 (genital herpes).
