Amylase, Body Fluid
Use
The test is used for the evaluation of patients with a pathological accumulation of fluid to determine whether pancreatic inflammation, pancreatic fistula, or esophageal rupture may be contributing. It also aids in the diagnosis of pancreatitis.
Special Instructions
For pancreatic cyst fluid specimens, order AMLPC / Amylase, Pancreatic Cyst Fluid. Testing will be changed to AMLPC if this test is ordered on that specimen type. Date and time of collection as well as the specimen source are required.
Limitations
In very rare cases, gammopathy, particularly type IgM (Waldenstrom macroglobulinemia), may cause unreliable results. Icodextrin-based drugs may lead to decreased amylase results. Results should be interpreted in conjunction with serum measurement, and specific for different body fluid types such as pleural, peritoneal, and drain fluid with respect to their comparison to serum amylase activity.
