Siemens Medical Solutions Diagnostics Announces Enhanced Liver Fibrosis Test for Europe

The First CE Marked, Non Invasive Blood Test for liver fibrosis is Available Through iQur, Ltd

TARRYTOWN, N.Y. & SOUTHAMPTON, England--(HSMN NewsFeed)--Siemens Medical Solutions Diagnostics ( today announced the availability of its Enhanced liver fibrosis (ELF)(TM) test, the first CE-marked, standardized non-invasive blood test for assessing the status of liver fibrosis*. The Siemens ELF test was first validated in an international multicenter cohort study and is now available through iQur, Ltd., Southampton, UK, as a testing service for patient management.

Chronic liver disease, resulting from alcoholic liver disease, fatty liver, or viral hepatitis, is increasingly recognized as a major cause of morbidity and mortality. Standard liver function tests do not accurately reflect the true extent of fibrotic damage or, in many cases, may detect it too late.

Fibrosis is a common outcome in chronic liver disease, with progression to cirrhosis accounting for thousands of deaths each year. Liver biopsies are routinely performed to assess liver damage (fibrosis) and to try to monitor the effectiveness of pharmaceutical drugs in tackling the disease. Performing a liver biopsy is a hazardous, expensive and painful experience for the patient and does not always provide accurate results because of difficulties in sampling and interpretation. Fibrosis is not evenly distributed throughout the liver and because such a small amount of biological material is sampled, 55 percent of 15mm biopsies may be misclassified. Larger biopsies can be performed but even with 25mm sections, 45 percent will be erroneous.

Because ELF uses a blood sample rather than a biopsy, it can be used routinely for the same patient and helps monitor progression of fibrosis in the patient's liver.

"The benefit of the Siemens ELF test is that it can be used repeatedly, with minimal patient discomfort, to monitor disease progression and response to therapy," said David Okrongly, senior vice president, Molecular Business Unit, Siemens Medical Solutions Diagnostics. "It's the first standardized laboratory method for assessment of liver fibrosis which requires only a simple sample of blood. We are delighted that iQur now offers this ELF test as an incremental service for physicians managing patients with chronic liver disease."

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, avoiding the need for a patient to travel to a hospital.
