Tests		Comments
Complete blood count		Elevated with infection, abscess
Serum amylase and lipase		Nonspecific for chronic pancreatitis1,2,16,18
Total bilirubin, alkaline phosphatase, and hepatic transaminase		Elevated in biliary pancreatitis and ductal obstruction by strictures or mass16
Fasting serum glucose		Elevation suggests pancreatic diabetes2
Pancreatic function tests		Sometimes useful in early chronic pancreatitis with normal computed tomography or magnetic resonance imaging1,2,5,19,20
	Fecal fat estimation	> 7 g fat per day is abnormal; quantitative; requires 72 hours; should be on a diet of 100 g fat per day1,2,5
	Fecal elastase	< 200 mcg per g (0.20 g per kg) of stool is abnormal; noninvasive; exogenous pancreatic supplementation will not alter results; requires only 20 g of stool2,5,19
	Secretin stimulation	Peak bicarbonate concentration < 80 mEq per L (80 mmol per L) in duodenal secretion; best test for diagnosing pancreatic exocrine insufficiency1,2,5,20
	Serum trypsinogen	< 20 ng per mL (0.83 nmol per L) is abnormal2,5
Lipid panel		Significantly elevated triglycerides are a rare cause of chronic pancreatitis2
Calcium		Hyperparathyroidism is a rare cause of chronic pancreatitis2
Immunoglobulin G4 serum antibody, antinuclear antibody, rheumatoid factor, erythrocyte sedimentation rate		Abnormality may indicate autoimmune pancreatitis10
