PlexPCR® VHS
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
Simplify lesion diagnostics
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.
- Validated on genital and non-genital samples
SpeeDx analysis software is included in contract pricing, is license free, and installed on a high security and GDPR compliant platform. Designed to support the IVD laboratory environment, features include:
- audit trails
- user traceability
- LIS connectivity
- QA and batch management

Evaluation of PlexPCR® VHS for diagnosis of genital lesions
Used PlexPCR® VHS to test 211 samples consisting of genital, anal/rectal, oral and non-genital swabs. Sensitivity/specificity of each target compared to in-house qPCR was 100%/99.4% for HSV-1, 96.0%/98.8% for HSV-2, 100%/100% for VZV and 100.0%/100.0% for TP.
SPEEDX PLEXPCR™ VHS EVALUATION
Used PlexPCR® VHS to test 373 genital and non -genital swab samples compared to in-house method. Prevalence for each target: HSV-1 24%, HSV-2 21.3%, Syphilis 1.7% VZV 0.3%. Sensitivity and specificity of 96-100% across targets.
Validation of PlexPCR® VHS Assay – Symposium Presentation
Goldstein et al. SpeeDx Satellite Symposium (ECCMID) April 14, 2019, Amsterdam, Netherlands.
Discusses rising rates of Syphilis and the importance of including molecular tests when diagnosing symptomatic lesions. Assesses PlexPCR® VHS test for lesion diagnostics and identifies positive syphilis samples that would otherwise not have been screened using serology.
