Siemens is marketing the first rapid, automated biomarker test for diagnosing and assessing liver fibrosis. The ELF test (Enhanced Liver Fibrosis test) takes approximately one hour to complete and requires only a blood sample. The process is therefore less inva-sive but just as reliable as the previously required biopsy, and it usually takes about a week to deliver a biopsy result. The new test was developed by Siemens Healthcare in collaboration with University College London and can be used as a routine test on the Siemens ADVIA Centaur Immunoassay System.
