Lipase, Serum
Clinical Information: Lipases are enzymes that hydrolyze glycerol esters of long-chain fatty acids
and produce fatty acids and 2-acylglycerol. Bile salts and a cofactor, colipase, are required for full
catalytic activity and greatest specificity. The pancreas is the primary source of serum lipase. Both lipase
and colipase are synthesized in the pancreatic acinar cells and secreted by the pancreas in roughly
equimolar amounts. Lipase is filtered and reabsorbed by the kidneys. Pancreatic injury results in increased
serum lipase levels.
Useful For: Investigating pancreatic disorders, usually pancreatitis
Interpretation: In pancreatitis, lipase becomes elevated at about the same time as amylase (in 4-8
hours). But lipase may rise to a greater extent and remain elevated much longer (7-10 days) than amylase.
Elevations 2 to 50 times the upper reference have been reported. The increase in serum lipase is not
necessarily proportional to the severity of the attack. Normalization is not necessarily a sign of resolution.
In acute pancreatitis, normoamylasemia may occur in up to 20% of such patients. Likewise, the existence
of hyperlipemia may cause a spurious normoamylasemia. For these reasons, it is suggested that the 2
assays complement and not exclude each other, and that both enzymes should be assayed.
