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

Multiplex PCR testing of anogenital lesions for Treponema pallidum and Herpes simplex virus in primary care improves the detection of Primary Syphilis.
Hughes, et. al. STI&HIV2023 World Congress, July 24 – 27, 2023 Chicago, USA.
Multiplex PCR testing for syphilis and herpes in primary care resulted in the detection of additional cases of primary syphilis. This is likely to have led to earlier diagnosis, treatment and potentially reduced infectiousness.
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.

Goldstein EJ et al Diagn Microbiol Infect Dis. 2020; 99(2):115221
Used PlexPCR® to test 250 previously tested patient samples. The overall agreement between the PlexPCR® VHS and in-house assays was 97%. Negative agreement was ≥99%, and positive agreement for individual targets was 96% (47/49) for T. pallidum, 98% for HSV-1 and HSV-2 (50/51), and 100% (51/51) for VZV.

Qquellon-Palacios J et al. STI & HIV 2021 World Congress 14th-17th July.
Screened 72 genital and extragenital lesions with PlexPCR® VHS compared with conventional PCR for TP screening. Use of PlexPCR® VHS increased the detection of TP and other STI pathogens.
