A
Liver enzymes
AST?
Increases rapidly with liver damage and clears quickly after damage ceases
ALT?
Increase slowly with hepatic damage and decreases slowly. Greatest elevation in acute hepatitis and drug reaction
ALP? Levels increase in response to biliary obstruction and sensitive indicator of intra and extrahepatic cholestasis
GGT? Marked elevation in obstructive jaundice, hepatic metastasis; intrahepatic cholestasis.
Elevation mirrors ALP elevation
Fatty Liver: ALT:AST ratio > 1
