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.

site of lesion; age at time of sample collection or date of birth, and sex.

- Sample was collected in universal viral transport media, using a plastic shaft swab
made of either polyester, cotton, rayon or Dacron.

- There is sufficient residual sample to perform both test and reference assays.
