Evaluate the enterohepatic cycle consisting of the biliary system, intestine, portal circulation, and hepatocytes.

  

Patient should be fasting; however, a two-hour postprandial level has been used by various physicians in order to evaluate hepatic function after the gallbladder has been completely emptied (ie, challenge the liver with a high level of bile acids in the portal circulation).

For women with intrahepatic cholestasis of pregnancy who need peak bile acid testing, samples may be taken postprandially.
