Lipase is an enzyme primarily produced by the pancreas to help digest dietary fats. Lipase is usually present in the blood in small quantities. When cells in the pancreas are injured, increased amounts of lipase enter the blood and result in higher concentrations in the blood. This can occur in conditions such as pancreatitis, or when the pancreatic duct is blocked by a gallstone or rarely by a pancreatic tumor. Serum/heparin plasma are recommended specimen
