Lipase, Serum

Test ID: 

703022

CPT code:

83690

Clinical Use:

Diagnose pancreatitis, more specific for pancreatitis than is serum amylase; diagnose peritonitis, strangulated or infarcted bowel, pancreatic cyst

Test Information:

Serum lipase is usually normal in patients with elevated serum amylase, without pancreatitis, who have peptic ulcer, salivary adenitis, inflammatory bowel disease, intestinal obstruction, and macroamylasemia. Coexistence of increased serum amylase with normal lipase may be a helpful clue to the presence of macroamylasemia.1 Lipase is elevated with amylase in acute pancreatitis, but the elevation of lipase is more prolonged.
