Serum bile acids and the assessment of hepatic function in dogs and cats.

Abstract

Current literature in veterinary internal medicine regarding the clinical use of the serum bile acids test to assess hepatobiliary function in dogs and cats is reviewed. The test is best used in cases where clinical signs and routine laboratory tests are suggestive of liver disease. It is a highly sensitive and specific test of hepatic function, and is the best method of assessing liver function available to the private practitioner. Abnormal results do not determine etiology, severity, or prognosis of the disorder. They merely indicate the need for hepatic biopsy. The serum bile acids concentration should always be measured in both a fasting and a two-hour postprandial sample.
