Amylase, Isoenzymes
Also known as: AMYISO
Use
The Amylase, Isoenzymes test is used to differentiate between the salivary and pancreatic types of amylase found in the serum. It is commonly used to investigate pancreatitis, salivary gland diseases, and other conditions that may result in an increase in these enzymes. The test measures the activity levels of pancreatic and salivary amylase isoenzymes to help in the diagnosis and management of conditions affecting the pancreas or salivary glands.
Special Instructions
Specimens should be collected in a serum separator or plasma separator tube, with green (lithium heparin) tubes also acceptable. Specimen must be allowed to clot completely at room temperature before separation.
Limitations
The test is not suitable for determining pancreatic or salivary amylase levels in body fluids other than serum or plasma. Hemolyzed specimens may affect results and should be avoided. Care should be taken to separate serum or plasma from cells within two hours of collection to prevent degradation of the enzyme activity.
