Reference Intervals
Interpretation
The preprandial bile acid value is sometimes increased relative to the postprandial bile acid value due to contraction of the gall bladder in the absence of gastric emptying. This may occur with habituation of the animal to eating at a certain time of day or may be stimulated by smell of food. If this happens, the serum bile acid values for both baseline and postprandial samples should be compared to the reference range listed for the postprandial bile acid.
