Serum Amylase (Enzymatic Method)
This test measures the level of amylase, an enzyme produced by the pancreas and salivary glands that helps break down carbohydrates. High levels may signal conditions like pancreatitis or other digestive issues.

Why Is This Test Done?
Your doctor may order a serum amylase test to check for conditions affecting the pancreas, such as pancreatitis, or to evaluate symptoms like abdominal pain, nausea, or unexplained weight loss. It can also help diagnose conditions like salivary gland inflammation or certain infections.
What Does a High or Low Level Mean?
Elevated amylase levels often indicate acute pancreatitis, salivary gland disorders, or other digestive issues. Very low levels are rare and may suggest rare metabolic or genetic conditions. Results alone don’t diagnose a specific condition; they’re usually reviewed with other symptoms and tests.
How Is the Test Performed?
A blood sample is taken from a vein in your arm. The sample is sent to a lab where it’s analyzed using an enzymatic method to measure amylase activity. You may feel slight discomfort, but it’s a quick and painless procedure.
What Are Common Symptoms Linked to Amylase Levels?
High amylase levels are often tied to abdominal pain, vomiting, diarrhea, or swelling in the pancreas. Symptoms like these should prompt medical attention, as they may require prompt treatment.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Serum amylase is a critical marker for diagnosing acute pancreatitis, salivary gland disorders, and other conditions affecting carbohydrate digestion. It helps doctors assess severity, guide treatment, and monitor recovery by detecting early changes in enzyme activity.
