Bile culture

Alternative names
Culture - bile

Definition
Bile culture is a test to detect infection in the biliary (liver secretion) tract.

How the test is performed
Through surgery or a procedure such as ERCP (endoscopic retrograde cholangiopancreatography), a specimen of bile is obtained for examination in the laboratory. It is placed in culture media and observed for growth of microorganisms that are then identified. The specimen may be obtained during or after gallbladder surgery from a tube to drain bile. A specimen may possibly be obtained during a radiology procedure to evaluate the gallbladder or biliary (liver secretion) system.

How to prepare for the test
The culture is usually tested in association with another procedure or surgery (see the specific procedure).

Infants and children:
