A liver biopsy is a procedure in which a small needle is inserted into the liver to collect a tissue sample. The tissue is then analyzed in a laboratory to help doctors diagnose a variety of disorders and diseases in the liver.
Non-alcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease worldwide and its prevalence continues to increase with the growing outbreak of obesity. NAFLD includes wide spectrum of diseases from fully benign simple steatosis to steatohepatitis, which could progress to liver cirrhosis and hepatocellular carcinoma. Liver biopsy is considered as the gold standard for assessing disease severity.
