Ver el código de «ALT»

==Background==
*Alanine aminotransferase; more specific to the liver than AST
*Found primarily in hepatocytes

==Normal Values==
*Normal: 7-56 U/L

==Interpretation==
*Most specific widely-available marker of hepatocellular injury
*ALT >1000 U/L: [[Acetaminophen toxicity|acetaminophen toxicity]], ischemic hepatitis, acute viral hepatitis, acute biliary obstruction
*Mild elevations (1-3x normal): fatty liver, medications, chronic hepatitis, celiac disease
*Moderate elevations (3-10x normal): acute/chronic hepatitis, autoimmune hepatitis, medications
*ALT may be normal in advanced cirrhosis (insufficient hepatocytes to release enzyme)
