Serum Amylase Test
The Amylase Blood Test measures the level of amylase, an enzyme produced mainly by the pancreas and salivary glands, in a blood sample. It is used to support the evaluation of pancreatic and related digestive conditions.

Quick answer
The Amylase Level Test is a blood test that measures amylase, an enzyme that helps break down starches. Amylase is produced mainly by the pancreas and salivary glands, and levels can change when these tissues are irritated or inflamed. The test is commonly ordered with lipase and other markers when a pancreatic problem or an abdominal issue is being evaluated. A qualified healthcare provider interprets the result with symptoms and other findings.
What this test measures
Amylase is an enzyme that breaks starch into smaller sugars. Most of it comes from the pancreas, with additional amounts from the salivary glands. Because the enzyme is concentrated in these tissues, changes in the blood level can provide clues about pancreatic or salivary gland irritation, inflammation, or blockage. Results are always considered alongside symptoms and other laboratory values.
The test uses a blood sample drawn from a vein, and no special collection equipment is usually needed. Laboratories report the total amylase level, and some can measure pancreatic and salivary isoenzymes separately when the source needs clarification. Lipase, another pancreatic enzyme, is often ordered at the same time because the two markers are interpreted together.
Amylase testing is requested when a clinician is evaluating upper abdominal pain, nausea, or other symptoms that could involve the pancreas. It may also be used to follow a known condition, and occasionally to investigate salivary gland problems. A single value rarely tells the whole story, so it is interpreted with the full clinical picture by a qualified healthcare provider.
- Amylase, total
- Pancreatic amylase isoenzyme (P-isoamylase)
- Salivary amylase isoenzyme (S-isoamylase)
- Lipase when ordered together
- Macroamylase evaluation when indicated
- Creatinine when ordered with a metabolic panel
Why people order this test
- Evaluate upper abdominal pain that may involve the pancreas
- Follow up on symptoms such as nausea, vomiting, or abdominal tenderness
- Monitor a known pancreatic condition over time
- Investigate possible salivary gland problems
- Support the assessment of unexplained enzyme elevation
- Complement lipase testing for a fuller picture
How to prepare
No fasting is usually required for an amylase test, although your ordering provider may ask you to fast if other tests are being collected at the same time. Tell the laboratory about any medications you take, since some can influence amylase levels.
Understanding your results
Results are typically available within one to three business days. The report shows the amylase value and its reference range. Elevated or reduced levels can have several explanations, so a qualified healthcare provider interprets the result together with symptoms, other enzyme tests, and imaging when needed.

Frequently Asked Questions
What is amylase?
It is an enzyme that helps digest starches. Most amylase comes from the pancreas, and smaller amounts come from the salivary glands.
Why is amylase tested with lipase?
Both are pancreatic enzymes. Ordering them together gives a clearer picture than either test alone when pancreatic involvement is suspected.
Does the test require fasting?
Usually not, but fasting may be requested if other tests require it. Follow the instructions from your ordering provider.
Can a normal amylase level rule out a pancreatic problem?
No. Normal results do not exclude every condition, and amylase can be normal in some pancreatic problems. The result is interpreted with other findings.
What can cause elevated amylase?
Pancreatic and salivary gland conditions are common causes, and other factors can also influence the level. A qualified healthcare provider can explain what an elevated value means.
