Elevated AST: Sensitivity and Specificity
Sens for Cholestasis = 28% (mild), 88% (severe)
Sens for Parenchymal = 70% (mild), 85% (severe)
Note that AST (but not ALT) is often elevated in MIs, though this particular study found the specificity of AST and ALT to be the same in patients with MI.
50% sensitive, 82% specific
74% sensitive, 92% specific
