Clinical Significance
This panel includes nucleic acid amplification testing for HSV-1, HSV-2, and Treponema pallidum in genital lesion swabs. Due to the overlapping clinical presentation of herpetic and syphilitic lesions, this panel can be used to aid in the identification of the most common etiological agents causing genital ulcer disease. A positive result is definitive diagnosis for the causative agent and a negative result may require additional testing.
