What is this test?
The urine amylase test measures the amount of amylase in your urine. Amylase is an enzyme produced mainly by the pancreas and salivary glands that helps your body break down carbohydrates and starches into sugar. When the pancreas or salivary glands are damaged or inflamed, amylase levels in the blood and urine increase. This test helps your healthcare provider evaluate how well your pancreas is functioning and check for conditions affecting the pancreas or kidneys.
How is the test performed?
For this test, you will need to provide a urine sample. Your healthcare provider may ask you to collect urine over a 24-hour period (called a 24-hour urine collection) or provide a single random urine sample. For a 24-hour collection, you will be given a special container to collect all urine produced during a 24-hour period. It's important to follow the instructions carefully, including storing the sample properly and keeping it refrigerated if required. Make sure to label the container with your name, date, and time of collection.
How to prepare for the test?
Before the test, tell your healthcare provider about all medications you are taking, as certain drugs can affect amylase levels. You may need to fast (not eat or drink) for a certain period before the test, as instructed by your provider. Follow any specific instructions given to you regarding diet, medications, or sample collection timing. Drink adequate water unless otherwise directed, as staying hydrated helps with urine collection.
What do the results mean?
Normal amylase levels in urine vary depending on the laboratory and the reference range used. High levels of amylase in urine (called amylasuria) may indicate acute pancreatitis, chronic pancreatitis, pancreatic cancer, gallstones, kidney disease, or salivary gland inflammation. Low levels may rarely indicate liver disease or chronic pancreatitis. Your healthcare provider will interpret your results based on your symptoms, medical history, and other test results. Do not interpret your results on your own—always discuss them with your doctor.
Are there any risks?
The urine amylase test is generally safe and has minimal risks. You may experience mild discomfort during urine collection. For 24-hour collection, keeping the container refrigerated may be inconvenient. There are no significant health risks associated with this test. If you have questions or concerns about the procedure, talk to your healthcare provider.
