Profile 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).
