The Test Sample
What is being tested?
Amylase is secreted through the pancreatic duct into the first part of the small intestine (duodenum), where it helps break down dietary carbohydrates. It is also produced by other organs, particularly the salivary glands.
Amylase is usually present in the blood and urine in small quantities. When cells in the pancreas are injured, as happens with pancreatitis, or when the pancreatic duct is blocked by a gallstone or by a pancreatic tumor in rare cases, increased amounts of amylase are released into the blood. This increases concentrations of amylase in the blood and also in the urine as amylase is eliminated from the blood through the urine.
