What is this test?
The 24-hour urine amylase test measures the amount of amylase enzyme in your urine over a 24-hour period. Amylase is primarily produced by the pancreas and salivary glands, helping to break down carbohydrates in the food you eat. When the pancreas is healthy, it releases a consistent amount of amylase into the digestive tract. However, when the pancreas becomes inflamed or damaged, amylase levels can increase significantly in the blood and urine.
How is the test performed?
You will receive a special container from your healthcare provider for urine collection. On the first day, you will begin collecting urine by first emptying your bladder in the morning and noting the time. All urine produced after that time should be collected in the container for the next 24 hours. The container should be kept refrigerated or in a cool place during the collection period. At the end of 24 hours, the final urine sample should be collected, and the entire collection is then taken to the laboratory for analysis.
How to prepare for the test?
Before the test, inform your doctor about all medications you are taking, as certain drugs can affect amylase levels. You may be asked to fast (not eat) for a certain period before the test. Avoid alcohol before and during the collection period. Your doctor may also instruct you to temporarily stop taking certain medications that could interfere with the results, such as some blood pressure medications, diuretics, or birth control pills.
