hepatocytes
Aminnotransferases (ALT and AST):
Levels > 1000 U/L extensive hepatocellular injury (viral
hepatitis, Ischemic Liver disease, Drug or Toxin induced)
In most acute hepatocellular damage ALT > AST
AST:ALT > 2:1 (suggestive) & > 3:1 (highly suggestive)
of (Alcoholic Liver Disease) ALD
Aminotransferases are usually not greatly elevated in
obstructive jaundice
