Primary Care is Missing 25% of Syphilis cases! Include T. pallidum detection in your genital lesion panel today. Read about this pivotal study below [1]

PlexPCR® VHS
Simplify lesion diagnostics
Detect and differentiate common lesion-causing pathogens Herpes simplex virus (HSV-1&-2), Varicella zoster virus (VZV) & Treponema pallidum (Syphilis) in a single-well multiplex qPCR test
Why use PlexPCR® VHS?
Syphilis rates are increasing around the globe, and symptomatic or visual lesion diagnostic approaches may be missing some cases presenting as an atypical lesion. Molecular diagnostics are recommended for management of genital lesions to improve diagnostic accuracy and subsequent patient management.
Ulcerations or lesions in the ano-genital and oral regions can be caused by a variety of bacterial and viral infectious agents.
Syphilis lesions can present atypically, be painful, and appear indistinguishable from herpes.
Up to 3% of genital lesions may be atypical zoster (VZV) presentations.
Validated on hundreds of clinical samples, PlexPCR® VHS demonstrates excellent sensitivity and specificity.

PlexPCR® VHS workflow solution
Streamline your workflow and increase productivity for rapid, routine diagnostics. Full automation options include sample and qPCR set-up, through to validated software solutions for automated result calling and simple data processing.
Detect all four common lesion-causing targets or choose to detect herpes and varicella only.
