Second podcast interview now available on the non-invasive assessment of liver fibrosis

In the second instalment of our podcast series on Advances in Laboratory Diagnostics, Clinical Diagnostics Editor, Sonia Nicholas, interviews Dr Navasa from the Hospital Clinic Barcelona, Spain. Dr Navasa and his team have been working on a partnership with Siemens Healthcare to use advanced laboratory and imaging technology to improve patient care management.

Liver fibrosis is the scarring process that represents the liver’s response to injury. Skin and other organs of the body heal wounds through the deposition of collagen and other matrix constituents. The liver also repairs injury in this manner, through collagen deposition. Over time, this process can result in cirrhosis of the liver, in which the architectural organization of the functional units of the liver becomes so damaged that blood flow through the liver, and liver function become disrupted. Once cirrhosis has developed, serious complications can occur such as portal hypertension, liver failure and liver cancer. The risk of liver cancer is greatly increased once cirrhosis develops.

Dr Navasa and his team have been using the Siemens ADVIA Centaur® Enhanced Liver Fibrosis (ELFTM) Test, in conjunction with advanced imaging techniques for the non-invasive assessment of liver fibrosis. The recent introduction of these advanced tools is enabling physicians to more closely monitor disease progression, and adjust treatment strategies accordingly.

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 the ELF test uses a blood sample rather than a biopsy, it can be used routinely for the same patient over time. The test combines three serum biomarkers, hyaluronic acid (HA), procollagen III amino terminal peptide (PIIINP), tissue inhibitor of metalloproteinase 1 (TIMP-1), which have been shown to correlate to the level of liver fibrosis assessed by liver biopsy.

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.

HematologyIn Haematology / Hematology, complete blood cell counts (or full blood counts) are obtained using automated blood count analyzers to enumerate blood cell types.  Hematology also encompasses haemostasis and coagulation, thrombophilia and hemophilia, plasma viscosity and ESR analysis, hemoglobinopathies, cell morphology and haematinic measurement.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.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. :In Vivo Imaging Systems<i>In vivo</i> imaging systems, including pre-clinical imaging systems and medical imaging systems are used to non-invasively visualize and capture images of live animals and plants. Monitor the natural processes or diseases of your subjects using small-animal pre-clinical imaging systems, including single photon positron emission tomography (SPECT), positron emission tomography (PET), computed tomography (micro-CT), magnetic resonance imaging (MRI), X-ray radiography, ultrasound, fluorescence and bioluminescence imagers. Multimodal systems and software solutions are also available for correlative analysis of organ, tissue, cell, or molecular-level processes. Find the best in vivo imaging products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Clinical ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.Liver Disease
