The invention concerns a method for the detection of the presence and/or the severity of a liver disease in a patient comprising measuring in an isolated sample TIMP-1 (tissue inhibitor of metalloproteinase I), ferritin , at least one additional parameter selected from the group consisting of A2M (alpha-2-macroglobulin) and PI (prothrombin index) and optionally measuring at least one additional biochemical or clinical parameter and diagnosing the presence and/or severity of a liver disease based on the presence or measured levels of these parameters. The method can be used for monitoring therapeutic treatment of liver fibrosis and staging of liver fibrosis.
