Pancreatic amylase in urine

Pancreatic amylase what is it?

Amylase is an enzyme that hydrolyzes starch and is produced in the pancreas and saliva. Amylase enters the blood if there is a duct obstruction or cell necrosis occurs. It is then excreted in the urine (with a delay of 8-10 hours).

In renal failure, urinary amylase has normal values or is reduced, while in plasma it may be increased A similar phenomenon is observed in macroamylasemia.
