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

ELF Test

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 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."
