Laboratory Findings

Complete blood count

• Neutrophilic leucocytosis

Cholestatic pattern of Liver function tests

• 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.
