Clinical Evaluation of the Sentosa SA HSV1/2 Qualitative PCR Test

This study will utilize residual samples from male and female patients with signs and symptoms of oral or genital HSV infections. Genital samples will include internal and external genital lesions such as those collected from lesions of the anus, buttocks, vagina, labia, or penis. Oral samples will include those collected from lip, gum, and mouth lesions. For concordance testing, the sample size is based on historical study design and estimates of the expected prevalence of HSV1 and/or HSV2 in the population enrolled.
