Clinical Benefits of The Enhanced Liver Fibrosis (ELF) Test
Assess the Risk of NAFLD/NASH Progression and Liver-related Events with a Simple Blood Test
The Enhanced Liver Fibrosis (ELF™) 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 chronic liver disease.
Why choose the ELF Test?
Clinical Benefits of ELF
The Enhanced Liver Fibrosis test is a simple blood test available to all healthcare practitioners and patients.
A simple blood test. Any patient. Any provider.
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.7,8
- Access non-invasive testing with a simple blood test available to all healthcare practitioners and patients, including those with type 2 diabetes mellitus and obesity.8,9
- Improve patient care by identifying NAFLD patients and stratifying those at risk of progressing to cirrhosis and LREs.10
- Enhance prognostic patient management with a test that has been shown to outperform biopsy for the risk assessment of progression to cirrhosis and LREs.10
ELF is featured in more than 200 peer-reviewed publications and has been evaluated in multiple forms of chronic liver disease
- Non-alcoholic fatty liver disease (NAFLD)
- Non-alcoholic steatohepatitis (NASH)
- Alcoholic liver disease (ALD)
- Primary sclerosing cholangitis (PSC)
- Primary biliary cirrhosis (PBC)
- Chronic HBV infection (CHB)
- Chronic HCV infection (CHC)
- Mixed chronic liver disease etiologies
In a UK study, the ELF test detected 5x more cases of advanced fibrosis, 3x more cases of cirrhosis, and reduced unnecessary referrals by 80%.
Reduce Unnecessary Referrals and Save Healthcare Costs
To reduce the burden of unnecessary referrals and improve detection of advanced liver disease, a “NAFLD pathway” was developed comprised of testing first with FIB-4 and reflexing indeterminate results to ELF. After 2 years the pathway data was compared to the Standard of Care.6
Multiple NAFLD/NASH International Clinical Guidelines Recommend ELF
The ELF Test is included in multiple international clinical guidelines supporting ELF both as a diagnostic and prognostic marker in NAFLD/NASH.
Diagnostic Accuracy and Cost-effectiveness
ELF Ranks First in Analysis of Cost-effectiveness
The population considered for analysis were persons with NAFLD who were suspected of having developed NASH with fibrosis or cirrhosis. This analysis found that, given a retesting frequency of 3 years, ELF was the highest ranking of the 13 tests compared at a cost-effectiveness threshold of £20,000 per QALY gained, followed by Siemens Healthineers ARFI.
The Guideline Development Group concluded that ELF is both the most cost-effective and the most appropriate test for advanced fibrosis in adults with NAFLD and should be offered to people with NAFLD.16
Advanced fibrosis test ranking based on diagnostic accuracy and cost-effectiveness
Cost-effectiveness = the value of the net monetary benefit (NMB) attributed to every test.
The comparator with the highest NMB is the most cost-effective option at the specified £20,000 per extra quality-adjusted life year (QALY) threshold.

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.
