Clinical Info

Non-invasive test that provides a simple, unitless numeric score that is generated via an algorithm for use in advanced liver fibrosis. It 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 nonalcoholic steatohepatitis (NASH), now called metabolic dysfunction-associated steatohepatitis (MASH), to assess the likelihood of progression to cirrhosis and liver-related clinical events

Result Interpretation

ELF™ Score Interpretation:

Risk cut-offs to assess the likelihood of progression to cirrhosis and liver-related clinical events within 3.9 years following baseline ELF score (IQR: 14.0-22.4 months):⁵

Lower risk	<9.80
Mid risk	9.80–11.29
Higher risk	>11.29
Note: The ELF™ Score is a unitless numerical value.
