Siemens Healthcare Diagnostics has announced that its Enhanced Liver Fibrosis (ELF)™ test* has been CE-marked for use on the ADVIA Centaur® Immunoassay Systems. This first fully automated standardised direct biomarker panel offers clinicians a quick, reliable, minimally invasive blood test option to assess liver fibrosis – a leading indicator of Chronic Liver Disease (CLD) – with results in less than one hour.

With the addition of the ELF test, Siemens is currently the only company to offer an integrated portfolio of diagnostic solutions for managing liver health, which includes routine chemistry tests, hepatitis serology tests, viral load testing, and ultrasound systems.

Liver fibrosis is an important indicator of CLD, such as cirrhosis and liver cancer, which are now among the top ten causes of death worldwide. i ii The ELF test is a simple, standardised blood test that assesses the severity of liver fibrosis by combining three direct serum biomarkers - hyaluronic acid (HA), procollagen III amino terminal peptide (PIIINP), and tissue inhibitor of metalloproteinase 1 (TIMP-1) - in an algorithm. The result is an ELF score, which correlates to the level of liver fibrosis assessed by liver biopsy,iii the current standard of care for liver fibrosis diagnosis.

“The discovery of the ELF markers represents a significant advance in the diagnosis of patients with liver disease,” said William Rosenberg, MBBS, D. Phil, Peter Scheuer Chair in Liver Diseases Joint Director of the Centre for Hepatology University College London. “Of particular benefit, the ELF test can help to identify 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.”

“While liver biopsy is the standard for assessing liver fibrosis, unfortunately, there are challenges with this procedure, including patient discomfort and difficulties in interpreting the results,” explains Dave Hickey, CEO, Chemistry, Immunoassay, Automation, and Diagnostics IT Business Unit at Siemens Healthcare Diagnostics. “By offering an automated, routine, minimally invasive blood test, Siemens provides an additional tool to physicians to aid them to easily assess the severity of liver fibrosis in their patients with chronic liver disease.”

The ELF test has been clinically validated on an Immuno-1 auto analyzer in an international multi-centre study with a mix of patient groups, including viral hepatitis, non-alcoholic fatty liver disease (NAFLD), and alcoholic patient groups. Additionally, a 7-year follow-up study involving over 450 patients has shown that the ELF markers are at least comparable to liver histology at predicting clinical outcomes of CLD.iv

MicroplatesMicroplates are multi-well plates used to increase the throughput of biological investigations. The number of wells microplates contain can range from 6 to 3243 wells, with the 96-well format being the most commonly used. Microplates can come tailored for a range of applications including cell culture, PCR, filtration, storage, non-binding surface, protein crystallization, as well as pre-coated, deep well and normal Standard microplates. Additionally, options for microplate colors include clear , black, white or black with clear bottom and white with clear bottom for absorbance microplate reader applications. Find the best microplates for your lab in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Microarray AnalysisMicroarrays, also known as biochips, are used for the detection and analysis of multiple genes, proteins, antibodies, or biomarkers on a single microchip. This can reveal information on protein or gene expression, single nucleotide polymorphism (SNP), copy number variation (CNV), epigenetics and patient health in clinical diagnostic tests. Discover a range of microarray scanners and prefabricated antibody, protein, RNA and DNA microarrays for your analysis or consider creating your own custom microarrays with a microarray printer. Find the best microarray products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Cell-Based AssaysCell-based assays are used to monitor the presence, quantity and activities of a desired cellular analyte including drug molecules or biomarkers. This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms. Find the best cell-based assay products, kits and equipment with our peer reviewed product directory: compare products, check customer reviews and receiving pricing direct from manufacturers.Point-of-CarePoint-of-Care Testing (POCT) or Near Patient Testing (NPT) products are available for urine, blood and other clinical chemistry analyses. POCT includes: blood glucose testing, blood gas and electrolytes analysis, rapid coagulation testing (PT / INR), rapid cardiac markers diagnostics, drugs of abuse screening, urine strips testing, pregnancy testing, fecal occult blood analysis, food pathogens screening, hemoglobin diagnostics, infectious disease testing and cholesterol screening.BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Clinical TrialsClinical Trials, an essential part of drug discovery process, assess the safety and effectiveness of a new medication or device in the pharmaceutical industry. Clinical Trials are a phased process (Phase 0, Phase I, Phase II, Phase III and Phase IV) which begins after initial preclinical testing.
