What is Aspartate Aminotransferase (AST)?
Aspartate Aminotransferase is measured as part of a liver function panel. Your AST is normal.
What does a high Aspartate Aminotransferase mean?
Elevated AST can indicate liver or heart damage. When both AST and ALT are high, it suggests liver disease. When AST is high alone, heart or muscle issues may be involved.
If markedly elevated: Your AST is critically high, indicating significant organ injury. Please see a doctor.
What does a low Aspartate Aminotransferase mean?
Low AST is rarely significant.
