A bile culture is a laboratory test to detect disease-causing microorganisms in the biliary system, which includes the gallbladder, bile ducts inside the liver, and bile ducts outside the liver.

See also: Bile

This test is done to detect infection within the biliary system. The biliary system creates, moves, stores, and releases bile to help in digestion.

A sample of bile (a digestive fluid) is needed. This can be done using different methods, including gallbladder surgery or a scope procedure called endoscopic retrograde cholangiopancreatography (ERCP).

For information on those procedures, see:

• ERCP
• Gallbladder surgery

The bile fluid sample is sent to a laboratory, where it is stored in a special dish (called a culture medium). The laboratory team watches to see if any bacteria, virus, or fungus grows on the sample.

Preparation depends on the specific method used to obtain the bile sample.

A culture does not involve the patient, so there is no pain.
