High amylase may occur with acute pancreatitis, salivary-gland disorders, pancreatic or bile-duct obstruction and other conditions; lipase provides additional pancreatic context.

What does the test measure?
The Amylase test measures the level of amylase, a carbohydrate-digesting enzyme produced mainly by the pancreas and salivary glands.
Why is the test ordered?
It is used especially when acute pancreatitis or other pancreatic disorders are suspected; amylase and lipase are often interpreted together with clinical findings.
Information about a low result
Low amylase may occur in some chronic pancreatic disorders or when pancreatic function is markedly reduced, but it does not diagnose pancreatic insufficiency by itself.
Information about a high result
High amylase may occur with acute pancreatitis, salivary-gland disorders, pancreatic or bile-duct obstruction and other conditions; lipase provides additional pancreatic context.

This is sourced reference/clinical-context information and should not be used alone as a diagnosis or treatment decision. The laboratory report, medication use and clinical context take priority.
Reference ranges may vary by laboratory, method used, age, sex, pregnancy status, and clinical context. The reference range on your own laboratory report takes precedence.
Interpretation notes
Amylase also comes from salivary glands. In suspected pancreatitis, lipase generally provides more pancreas-specific information; results are interpreted with symptoms and imaging.

Frequently asked questions
No. Laboratory results are interpreted with symptoms, medical history, specimen conditions and related tests.
Start with the performing laboratory's own reference interval; clinical cutoffs, when relevant, are separate sourced thresholds used for a specific purpose.
Results that are clearly outside range, persistent, symptomatic or unexpected should be reviewed by a healthcare professional.
