2026-03-22T06:58:09Z
<p>Create lab page for AST with EM-focused content and references</p>
<p><b>New page</b></p><div>==Background==<br />
*Aspartate aminotransferase; found in liver, heart, muscle, kidney, and red blood cells<br />
*Less specific for liver injury than ALT<br />
<br />
==Normal Values==<br />
*Normal: 10-40 U/L<br />
<br />
==Interpretation==<br />
*AST:ALT ratio >2:1 suggests alcoholic liver disease<br />
*AST:ALT ratio <1 is more typical of non-alcoholic fatty liver disease or viral hepatitis<br />
*AST >1000 U/L: acute viral hepatitis, ischemic hepatitis (shock liver), acetaminophen toxicity, acute biliary obstruction<br />
*Elevated AST without elevated ALT: myocardial injury, rhabdomyolysis, hemolysis (non-hepatic sources)<br />
<br />
