Clinical Info

Evaluate parotitis and pancreatic disease. Amylase is primarily produced in the pancreas and salivary glands. Isoenzymes may be used to determine the source of an 
elevated amylase concentration. Measurement of pancreatic amylase activity is of value in diagnosing pancreatitis and other pancreatic disorders that result in the elevation 
of serum and urine amylase.

Methodology

Total amylase: enzymatic; pancreatic and salivary amylase: salivary amylase is inhibited by specific antibodies and the remaining pancreatic amylase is determined by an enzymatic, 
colorimetric method. Salivary amylase is calculated as the difference between the total and pancreatic amylase.
