ELF™ Test Now available!
ELF*: The first CE marked Liver Fibrosis Marker Panel

The ELF test is a simple, accurate, minimally-invasive blood test for measuring liver damage (known as fibrosis). It offers a quick straightforward method of providing valuable information:


  • Minimal or no patient discomfort
  • Identifies significant liver disease


Because ELF uses a blood sample rather than a biopsy, it can be used routinely for the same patient over time.

The ELF test - Three serum biomarkers

The ELF test combines three serum biomarkers which have been shown to correlate to the level of liver fibrosis assessed by liver biopsy. These biomarkers include:


  • Hyaluronic acid (HA)
  • Procollagen III amino terminal peptide (PIIINP)
  • Tissue inhibitor of metalloproteinase 1 (TIMP-1)


The algorithm measures each of these markers by immunoassay, to create an ELF score. Sampling for the ELF test can be performed in a physician’s office or health center.

"The discovery of the ELF markers represents a significant advance in the diagnosis of patients with liver disease. Of particular benefit, the ELF test can help diagnose patients with mild-to-moderate liver fibrosis, which is usually asymptomatic, so that clinicians are able to intervene before significant damage to the liver occurs."
