Test Classification
This test has been cleared, approved, or is exempt by the US Food and Drug Administration and is used per manufacturer's instructions. Performance characteristics were verified by Mayo Clinic in a manner consistent with CLIA requirements.Secondary ID
604930Profile Information
Test ID | Reporting Name | Available Separately | Always Performed |
---|---|---|---|
AMYSE | Amylase, Total, S | Yes, (Order AMS) | Yes |
AMYPA | Amylase, Pancreatic, S | No | Yes |
AMYSA | Amylase, Salivary, S | No | Yes |
Testing Algorithm
Total and pancreatic amylase are measured in the submitted serum specimen. Salivary amylase is calculated as the difference between the two measured results (salivary amylase = total amylase-pancreatic amylase).
Forms
If not ordering electronically, complete, print, and send Gastroenterology and Hepatology Test Request (T728) with the specimen.
