The aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio is a calculation derived from the levels of two liver enzymes found in the blood. This ratio is determined by dividing the AST value by the ALT value. The result can offer valuable insights into potential liver damage and its possible causes. For example, a ratio greater than one may suggest alcoholic liver disease, while a lower ratio might indicate other forms of liver injury.
The significance of this calculation lies in its ability to provide clues about the nature and severity of liver ailments. Historically, this ratio has been used as a diagnostic aid, particularly in distinguishing between different types of hepatic disorders. It serves as a readily accessible tool for healthcare professionals, assisting them in the initial assessment of liver function and informing further diagnostic investigations. The utility of this calculation extends to monitoring disease progression and evaluating treatment efficacy.
