General Overview

WOUNDCHEK™ Laboratories is focused on the development of novel wound diagnostic products to help improve outcomes in wound care. Currently, the cost of ineffective treatment is estimated to be more than $20-25 billion¹Data based on savings calculated with the WOUNDCHEK economic model, UK version, with AQP VLU data inputs. – Nherera L. et al. Quantifying the economic value of diagnostics in wound care in the UK. Poster, EWMA 2013. annually. Clinical experts agree the use of point of care wound diagnostic devices could reduce the cost of ineffective treatment and delayed healing by being able to target the right therapy, on the right patient, at the right time, and for the right length of time²World Union of Wound Healing Societies (WUWHS). Principles of best practice: Diagnostics and wounds. A consensus document. London: MEP Ltd, 2008.. A resulting financial benefit to health care systems can be achieved through significant reduction of the expenses associated with poor targeting of treatment, delayed healing, and avoidable complications. WOUNDCHEK™ Laboratories launched the world’s first and only point of care test to detect EPA (elevated protease activity) in chronic wounds in 2012, and over the past several years has become a recognized leader in wound diagnostics. 


The company’s vision is to provide clinicians with better, accurate, timely, actionable, and easy to access information, leading to improved outcomes through point of care wound diagnostics. WOUNDCHEK™ Laboratories aims to be the leading and dominant enterprise in wound diagnostics by providing medical professionals with the diagnostic information to: 

  • Identify wounds which are not healing 

  • Intercept issues and early warnings that cause poor wound healing or initiate wounds 

  • Aid in determination of best therapeutic routes 

  • Monitor the effectiveness of a course of treatment


Based in the UK and the USA, WOUNDCHEK™ Laboratories' staff are focused on product development, clinical research, and working with its distribution partners to develop the emerging wound diagnostics market.

Our research is centred on two critical questions, identified by clinical experts as primary pieces of diagnostic information needed to direct treatment pathways in the majority of chronic wounds:

  • Does the wound have chronic inflammation?

  • Is there an active bacterial pathogenesis?

Bacterial Virulence

Bacterial proteases have been described as the most important class of virulence factors and play a key role in the establishment of wound infections, ultimately impeding the healing response and keeping the wound in a chronic state1Koziel J, Potempa J. Protease-armed bacteria in the skin. Cell Tissue Res. 2013; 351(2): 325-37.. They are produced by both Gram-negative and Gram-positive bacteria associated with chronic wound colonization2Wysocki AB, Bhalla-Regev SK, Tierno PM, Steven-Riley M, Wiygul R. Proteolytic Activity by Multiple Bacterial Species Isolated from Chronic Venous Leg Ulcers Degrades Matrix Substrates. Biol Res Nurs. 2012; 15(4): 407-415..

The detection of bacterial protease activity in a chronic wound would be indicative of the presence of bacterial virulence which is a precursor to clinical signs and symptoms of infection3Thomson PD, Smith DJ. What is infection? Am. J. Surg. 1994; 167(No. 1A): 7S-10S.,4Dow G, Browne A, Sibbald RG. Infection in chronic wounds: Controversies in diagnosis and treatment. Ostomy Wound Management 1999; 45 (8): 23-40. .

Bacterial virulence is undesirable since, at this stage, the wound is in a part of the wound infection continuum that typically requires intervention.

FDA clears WOUNDCHEK™ Bacterial Status for use by wound care professionals

Date: Dec 2, 2019

Woundchek Laboratories are excited to announce that the FDA has cleared Bacterial Status for use in the USA by health care professionals whose clinical practice primarily or routinely involves the assessment and treatment of chronic wounds.  Bacterial Status results are intended for use in conjunction with the assessment of other known risk factors for wound healing that significantly contribute to the assessment of risk for non-healing chronic wounds such as wound age, wound size, and vascular status.

Bacterial Status is intended for use in adult patients as an aid in assessing the risk for non-healing of chronic venous, diabetic foot, and pressure ulcers associated with wounds where patients are asymptomatic for clinical signs of infection.  The test is intended for use with chronic wounds that are between 21 days and < 6 months of age and chronic wounds that are > 6 months of age that are < 1cm2 in size.
