About AST/ALT Ratio

The AST/ALT Ratio tool is designed for clinicians and healthcare professionals to quickly calculate and interpret the ratio of Aspartate Aminotransferase (AST) to Alanine Aminotransferase (ALT) enzyme levels. This simple calculation (AST divided by ALT) serves as a valuable diagnostic aid in differentiating the etiologies of elevated liver enzymes. A ratio significantly greater than 1, especially above 2, strongly suggests alcoholic liver disease, while a ratio less than 1 is more common in conditions like non-alcoholic fatty liver disease or viral hepatitis. By providing rapid insight into potential liver pathologies, the tool supports informed clinical decision-making and helps guide further diagnostic steps and patient management.
