Just learned some new info on liver enzymes:
The diagnostic approach to asymptomatic dogs with elevated liver enzyme activities - Veterinary Medicine=
Basicly from the article:
If microcytic RBC's are present= Liver Shunt.
If ALT, ALP & AST are increased two-threefold = Liver Shunt
If ALT, ALP & AST are normal - mildly increased = MVD
Gallbladder Mucoleles increase ALT, AST, ALP, & GGT
Increase in Bilirubin & decrease in Albumin = need for diagnostic imaging and hepatic biopsy.
