Research in support of novel blood-based testing

MASH Clinical Evidence

Labcorp’s leadership position in metabolic dysfunction-associated steatohepatitis (MASH, formerly known as NASH) is highlighted by scientific innovation in the blood-based identification of at-risk MASH. With our deep biopharma experience, we provide a customized approach to biomarker solutions in drug discovery that supports decision-making from discovery to the clinic.

Non-Invasive Biomarkers of Metabolic Liver Disease (NIMBLE) 

Led by the Foundation for the National Institute of Health’s Biomarkers Consortium, the goal of the NIMBLE program is to test the performance of currently available, well-validated, non-invasive MASH tests and provide evidence of clinical utility. 

Stage 1 publication: The data supported the further development of NIS4® for its intended use to identify persons with at-risk MASH (nonalcoholic fatty liver disease activity score ≥4, liver fibrosis F≥2).
