Ver el código de «AST»

==Background==
*Aspartate aminotransferase; found in liver, heart, muscle, kidney, and red blood cells
*Less specific for liver injury than ALT

==Normal Values==
*Normal: 10-40 U/L

==Interpretation==
*AST:ALT ratio >2:1 suggests alcoholic liver disease
*AST:ALT ratio <1 is more typical of non-alcoholic fatty liver disease or viral hepatitis
*AST >1000 U/L: acute viral hepatitis, ischemic hepatitis (shock liver), acetaminophen toxicity, acute biliary obstruction
*Elevated AST without elevated ALT: myocardial injury, rhabdomyolysis, hemolysis (non-hepatic sources)
