Overview
Certain laboratory tests may be helpful in the diagnosis of cholangitis. Some commonly conducted tests include complete blood count, basic metabolic panel, liver function tests, blood culture, and other body fluid cultures.
Laboratory Findings
Laboratory findings typically associated with cholangitis include:[1][2]
Complete blood count (CBC):
Liver function tests (LFTs):
Cholestatic patterns of liver function tests may be remarkable for:[1][3][4][5]
- Elevated serum alkaline phosphatase (ALP)
- Elevated gamma-glutamyl transpeptidase (GGT)
- Elevated conjugated (direct) bilirubin (predominantly incase of obstruction)
- Elevated serum amylase (7%)
- Levels may be as high as 3-4 times of normal, representing pancreatitis.
- Culture from bile obtained during ERCP (endoscopic retrograde cholangiopancreatography)
- Elevated aminotransferases (as high as 1000 IU/L), reflecting hepatocytes injury and microabscess formation
- Liver abscess may be suspected in such cases.
- Liver enzyme abnormalities suggestive of cholestasis[2]
Blood cultures:
- Cultures are obtained from bile aspirated through percutaneous biliary catheters, obtained during biliary drainage, or from indwelling biliary prostheses.
