Understanding Your Laboratory Test: A Patient Guide to Testing and Results
A blood test that measures amylase enzyme levels to evaluate pancreatic and salivary gland function.
{"Amylase is an enzyme that helps digest carbohydrates, produced mainly by the pancreas and salivary glands","This test helps diagnose conditions affecting the pancreas such as pancreatitis","Abnormally high or low amylase levels may indicate pancreatic disease or other conditions","The test requires a simple blood draw, typically after fasting","Results are compared to a normal range that varies by laboratory"}

This test is a laboratory procedure that measures specific substances in a sample from your body, such as blood, urine, or tissue. Your healthcare provider uses the results to check how well your body is working and to help diagnose or monitor health conditions.
The amylase test measures the total amount of amylase enzyme in your blood. Amylase is a digestive enzyme produced primarily by two organs: the pancreas (which makes pancreatic amylase, also called S3 and S4) and the salivary glands (which make salivary amylase). This enzyme helps break down starches and carbohydrates into sugars that your body can use for energy.
Your doctor may order this test to find out what is causing your symptoms, to screen for certain health problems before symptoms appear, to see how well a treatment is working, or to monitor a condition you already have. The results provide important information that helps guide your care.
Your healthcare provider may order an amylase test to: evaluate pancreatic function, diagnose conditions like pancreatitis (inflammation of the pancreas), detect pancreatic cancer or pancreatic cysts, investigate causes of abdominal pain, monitor treatment for pancreatic diseases, or evaluate salivary gland problems.
The test is usually done in a clinic, hospital, or laboratory. Depending on the type of test, this may involve drawing blood from a vein in your arm, collecting a urine sample, or taking a small swab. The sample is sent to a laboratory, where trained staff analyze it and send the findings to your healthcare provider.
A healthcare professional will draw a small blood sample from a vein in your arm using a needle. The blood is collected into a tube and sent to a laboratory for analysis. You may be asked to fast (not eat or drink anything except water) for 8-12 hours before the test. It is important to follow your healthcare provider's instructions regarding fasting and any medications you may be taking.
Your results are compared with a reference range, which is the set of values typically seen in healthy people. A result outside this range does not always mean something is wrong, so it is important to review your results with your healthcare provider. They will explain what your numbers mean, whether follow-up testing is needed, and what the next steps should be for your care.
Normal amylase levels typically range from 23 to 85 units per liter (U/L), though the normal range may vary slightly between laboratories. Your result should always be interpreted by your healthcare provider who will consider your overall health, symptoms, and other test results. A single abnormal result does not necessarily mean you have a serious condition - your doctor may recommend additional tests to confirm a diagnosis.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Elevated amylase levels may indicate: acute or chronic pancreatitis, pancreatic cancer or pseudocysts, gallbladder disease, mumps or other viral infections affecting salivary glands, kidney disease, peptic ulcer disease, or certain medications. Significantly elevated levels (more than 3 times the upper limit of normal) are highly suggestive of acute pancreatitis.
Low amylase levels may be seen in: pancreatic insufficiency (when the pancreas cannot produce enough enzymes), chronic pancreatitis, severe liver disease, cystic fibrosis, or malnutrition. Abnormally low levels are less common but can indicate significant pancreatic damage.
