Type-specific testing for herpes simplex virus

Abstract

The prevalence of genital herpes is increasing worldwide. Type-specific antibody tests for herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) are widely available, however, only those based on glycoprotein G have acceptable accuracy. When diagnosing genital herpes, it is important to use type-specific tests in order to distinguish HSV-1 from HSV-2 since the type of HSV infection affects prognosis and subsequent counseling. Populations appropriate for type-specific serologic testing for HSV include people with an uncertain clinical diagnosis, high-risk patients, partners of an HSV-infected individual, HIV-infected individuals and pregnant women.
