De Ritis Ratio (Ast/Alt Ratio)

Description

The De Ritis Ratio has been used clinically and in research for almost 50 years and is simply the ratio of aspartate transferase to alanine transferase. Validated in many cohorts, interpretations vary, and as such, I simply define a ratio of above 0.8 as indicative of liver injury, commonly agreed upon in the literature.

Usage

Arguments

ast

Numeric value of aspartate transferase (U/L).

alt

Numeric value of alanine transferase (U/L).
