Dr. Center updated the protocol years ago and a 12 hour fast is no longer required:
Serum bile acids should be collected Before and 2-hours After a meal (this serves as a provocative challenge initiating bile acid release from the gallbladder, intestinal reabsorption, passage into the portal vein to the liver, and rapid liver extraction from the portal blood). The term Postprandial refers to the after meal sample. Dogs DO NOT need to be fasted for 12-hours to conduct this test. The important issue is to test BEFORE and 2-Hrs after FEEDING to fully evaluate the dogs ability to extract bile acids from the portal circulation.
