Amylase, Pancreatic Isoenzyme, Salivary Isoenzymes (calculated)
Amylase is produced primarily in the pancreas and salivary glands. Isoenzymes may be used to determine the source of an elevated amylase concentration. Macroamylase is a laboratory and not a clinical entity. Amylase can complex with immunoglobulins or other high molecular weight proteins and serum amylase will appear falsely elevated. No clinical symptoms are associated with macroamylasemia.
