De Ritis ratio

De Ritis ratio expresses the ratio of the catalytic concentration of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in the serum. If in hepatopathy AST / ALT is > 1, it is considered a sign of hepatocyte necrosis, and therefore more severe liver damage.

See also aminotransferase page for more detailed information.
