About APRI Index

The APRI Index (AST to Platelet Ratio Index) is a widely utilized non-invasive scoring system designed to assess the likelihood of significant liver fibrosis and cirrhosis. By integrating readily available routine blood test results – specifically aspartate aminotransferase (AST) levels and platelet count – this tool provides a simple, cost-effective method for clinicians to stratify patients. It serves as a valuable screening and monitoring instrument for healthcare professionals, including hepatologists and gastroenterologists, enabling earlier identification of advanced liver disease. The APRI Index helps guide clinical decisions, potentially reducing the need for more invasive diagnostic procedures such as liver biopsy, thereby improving patient care and resource allocation.
