A urine sample is needed. The test may be performed using a single urine sample or a 24-hour urine collection. For information on how to collect a sample, see:

• Clean-catch urine test
• 24-hour urine collection

Your health care provider may tell you to stop taking certain drugs that can affect test results. Drugs that can increase amylase levels include:

• Asparaginase
• Aspirin
• Birth control pills
• Cholinergic drugs
• Codeine
• Corticosteroids
• Indomethacin
• Loop and thiazide diuretics
• Methyldopa
• Morphine
• Pentazocine

The test involves only normal urination, and there is no discomfort.

This test is done to diagnose pancreatitis and other diseases that affect the pancreas. Your doctor may also order this test to see how treatment for such conditions is working.

The normal range is 2.6 to 21.2 international units per hour (IU/h).

Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

The examples above show the common measurements for results for these tests. Some laboratories use different measurements or may test different specimens.

An increased amount of amylase in the urine is called amylasuria. Increased amylase levels may be a sign of:

• Acute pancreatitis
• Alcohol consumption
• Cancer of the pancreas , ovaries, or lungs
• Cholecystitis
• Ectopic or ruptured tubal pregnancy
• Gallbladder disease
• Infection of the salivary glands (called sialoadenitis, may be caused bymumps or a blockage)
• Intestinal obstruction
• Pancreatic duct obstruction
• Pelvic inflammatory disease
• Perforated ulcer

Decreased amylase levels may be due to:

• Damage to the pancreas
• Kidney disease
• Pancreatic cancer
• Toxemia of pregnancy

There are no risks.
