Overview
Laboratory tests provide useful clues in the diagnosis of cholangitis. Some commonly conducted tests are complete blood count, basic metabolic panel, liver function tests, blood culture, and other body fluid culture.
Laboratory Findings
Complete Blood Count
- Neutrophilic leucocytosis[1]
Cholestatic Pattern of Liver Function Tests
Cholestatic patterns of liver function tests can indicate:[1][2][3]
- Blood culture
- Elevated serum alkaline phosphatase
- Elevated gammaglutamyl transpeptidase (GGT)
- Elevated conjugated (direct) bilirubin
- Elevated serum amylase
- 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 is indicated in such cases.
