Bile cultureDefinitionA bile culture is a laboratory test to detect disease-causing substances in the biliary system, which includes the gallbladder, bile ducts inside the liver, and bile ducts outside the liver. See also: Bile Alternative NamesCulture - bileWhy the Test is PerformedThis test is done to detect infection within the biliary system. The biliary system creates, moves, stores, and releases bile to help in digestion. How the Test is PerformedA 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). See also: The 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. How to Prepare for the TestPreparation depends on the specific method used to obtain the bile sample. See also: How the Test Will FeelA culture does not involve the patient, so there is no pain. See also: RisksA culture does not involve the patient, so there are no risks. Other risks depend on the method used to take a sample of the bile. Normal ResultsThe test result is normal if no bacteria, virus, or fungus grew in the laboratory dish. Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results. What Abnormal Results MeanAn abnormal result means bacteria, fungus, or virus grew in the laboratory dish. This may be a sign of infection.
