Hepatic fibrosis is an important consequence of inflammatory disorders affecting the liver, and ultimately progresses to cirrhosis. Here we explore methods for the detection and monitoring of hepatic fibrosis, particularly in hepatitis C, alcoholic liver disease, non-alcoholic fatty liver disease and during methotrexate therapy, in all of which progressive fibrosis can develop over a number of years in a minority of patients. Liver biopsy currently remains the gold standard to assess fibrosis. However, it has several limitations, including manpower issues, cost, risk of patient injury, including mortality and morbidity, observer variability and sampling variation. Several non-invasive diagnostic tests for fibrosis and cirrhosis have therefore been evaluated. The usefulness of a laboratory test for screening for a pathological abnormality such as fibrosis is critically dependent on the prevalence of the pathology in the population under investigation. When the prevalence is expected to be low, screening tests should have a high negative predictive value so that large numbers of patients can be spared the next diagnostic step, namely liver biopsy. For the moment, clinical chemistry laboratories should offer the aspartate aminotransferase alanine anninotransferase ratio, AST/platelet ratio and the Rosenberg fibrosis index as part of their routine service for monitoring the development of hepatic fibrosis.
