4-61 U/L |
Test Comments:
If Amylase Isoenzymes are >115 U/L, Macroamylase will be performed at an additional charge (CPT code(s): 82150
Methodology:
Polyethylene Glycol Precipitation
Clinical Significance:
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.
