Assess the Prognosis of Advanced Fibrosis due to NASH with a Simple Blood Test
Clinical Benefits of The Enhanced Liver Fibrosis (ELF™) Test

The Enhanced Liver Fibrosis test is a non-invasive blood test that measures three direct markers of fibrosis. Direct assessment of fibrosis has proven valuable for identifying patients at risk of progressing to cirrhosis and/or liver-related events.

The most widely studied direct marker is the ELF Test which can assess active, dynamic fibrosis rather than the damage it has caused. This allows the ELF Test to be used as a prognostic marker to identify the patients most at risk of progression to cirrhosis and LREs in patients with advanced fibrosis due to NASH.

ELF™ Test Now Included in Multiple Clinical Guidelines

American Association of Clinical Endocrinology

ELF was strongly recommended in the 2022 NAFLD Clinical Practice Guidelines
ELF testing can be incorporated into a clinical decision pathway to identify NASH patients at risk of progressing to cirrhosis

American Association of Clinical Endocrinology Clinical Practice Guideline for the Diagnosis and Management of Nonalcoholic Fatty Liver Disease in Primary Care and Endocrinology Clinical Settings (endocrinepractice.org)

American Gastroenterological Association

ELF was included in the 2022 Clinical Practice Update: Diagnosis and Management of Nonalcoholic Fatty Liver Disease in Lean Individuals: Expert Review
An ELF score of ≥ 9.8 is valuable for prognostic decision making

AGA Clinical Practice Update: Diagnosis and Management of Nonalcoholic Fatty Liver Disease in Lean Individuals: Expert Review (gastrojournal.org)

A simple blood test. Any provider. Any lab.

Blood-based tests can readily support high-volume testing, do not require patient access to specialized imaging equipment or highly trained operators, and generally have lower incidence rates of failure and unreliable results reported for imaging modalities.^1,2

Access noninvasive testing with a simple blood test available to all patients, including those with type 2 diabetes mellitus and obesity.^2,3
Improve patient care by stratifying advanced NASH patients most at risk of progressing to cirrhosis and liver-related events.⁴
Enhance patient management with a blood test that facilitates more frequent prognostic assessments

The products/features (mentioned herein) are not commercially available in all countries. Their future availability cannot be guaranteed.

*In the U.S., the ELF Test is indicated as a prognostic marker in conjunction with other laboratory findings and clinical assessments in patients with advanced fibrosis (F3 or F4) due to non-alcoholic steatohepatitis (NASH) to assess the likelihood of progression to cirrhosis and liver-related clinical events. The test is not for use in the diagnosis of NASH or for the staging of fibrosis.
