Performing Lab
Amylase Isoenzymes with Reflex to Macroamylase
Clinical Use
Order TestUse
Amylase is produced primarily by the pancreas and salivary glands. Measuring isoenzymes—pancreatic and salivary—can help determine the source of an elevated amylase. Macroamylase refers to amylase complexes with immunoglobulins or other high–molecular‑weight proteins, leading to falsely elevated serum amylase; macroamylasemia is a laboratory finding without associated clinical symptoms.
