Although the classical gold standard for diagnosing and staging non-alcoholic fatty liver disease (NAFLD) and assessing fibrosis is liver biopsy, the procedure has several drawbacks, such as sample error, subjectivity in interpretation, high cost, and a small but real risk of complications.In an attempt to replace liver biopsy and to subcategorize patients with NAFLD into different prognoses, many non-invasive methods using various biomarkers, scoring systems, and imaging methods, such as elastography, have been attempted in the last decade. This article summarizes non-invasive diagnostic tests for the diagnosis of NAFLD/Nonalcoholic steatohepatitis, as well as the limitations and merits of liver biopsy.
Key Words: Non-alcoholic fatty liver disease, Nonalcoholic steatohepatitis, Diagnosis, Liver biopsy
