This is a test that measures the amount of amylase in urine. Amylase is an enzyme that helps digest carbohydrates. It is produced mainly in the pancreas and the glands that make saliva.
Amylase may also be measured with a blood test. See: Amylase - blood
How the test is performedA 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:
How to prepare for the testYour 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
- Pentazocine
- Cholinergic agents
- Corticosteroids
- Indomethacin
- Loop and thiazide diuretics
- Methyldopa
- Codeine
- Morphine
- Birth Control pills
The test involves only normal urination, and there is no discomfort.
Why the test is performedThis 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.
Normal ValuesThe normal range is 2.6 to 21.2 international units per hour (IU/h).
What abnormal results meanAn increased amount of amylase in the urine is called amylasuria. Increased amylase levels may indicate:
- Acute pancreatitis
- Alcohol consumption
- Cancer of the pancreas, ovaries, or lungs
- Cholecystitis
- Ectopic or ruptured tubal pregnancy
- Gallbladder disease
- Infection of the salivary glands (mumps or an obstruction)
- Intestinal obstruction
- Pancreatic duct obstruction
- Perforated ulcer
Decreased amylase levels may be due to:
- Damage to the pancreas
- Kidney disease
- Pancreatic cancer
- Toxemia of pregnancy
There are no risks.

What enzyme dissolves starch?
Amylase enzymes.
What type of compound and bond is hydrolized by the alpha amylase?
Alpha bonds are hydrolised by alpha amylase. The alpha amylase is the sole form of amylase found in all mammals.
What is the difference between salivary amylase and pancreatic pytlin?
Salivary amylase breaks 1-4 Linkage whereas Pancreatic amylase breaks 1-6 linkage in Polysacharides
What macrmolecules are targeted by amylase?
Amylase targets starch. Specifically it targets the bonds between glucose molecules.
If your mouth produces amylase and your stomach is highly acidic what happens to the amylase when you swallow?
Amylase is an enzyme, which is a type of protein. Protein denatures when temperature or pH (acidity) is changed. for example, amylase will no longer digest starch if you put it in a boiling water bath for 5 minutes. in the stomach, hydrochloric acid is produced by the stomach lining to digest food. this acid will denature the amylase when the swallowed food mixed with amylase from the mouth enters the stomach.
Is amylase found in other parts of the digestive system?
Amylase is produced by the salivary glands and pancreas.In humans, amylase is found in saliva, blood, and urine. The majority of amylase is found in the mouth, this enzyme is the chemical digestion that breaks down starch into smaller saccharides.Under normal conditions only low levels are found in the blood and urine; higher levels are found if the pancreas or salivary glands become blocked or damaged. Therefore raised levels in the blood or urine can be indicators of pancreatic diseases (such as pancreatitis).
What enzyme dissolves starch?
Amylase enzymes.
What is the name of the enzyme that digests starch?
AMYLASE
Is ptylin an alpha amylase or beta amylase?
Ptyalin is an alpha-amylase. It is the alpha-amylase found in saliva
What dissolves starch?
amylase:) amylase:)
Where is amylase released?
The enzyme amylase is released in the mouth, referred as the salivary amylase, and in the duodenum of the small intestine by the pancreas, referred as the pancreatic amylase.
What Enzymes are responsible for breakdown of starches?
They are Broken down by Amylase Enymes.
Macroamylasemia?
DefinitionMacroamylasemia is the presence of an abnormal substance called macroamylase in the blood.Causes, incidence, and risk factorsMacroamylase is a substance that consists of an enzyme, called amylase, attached to a protein. Because it is large, macroamylase is filtered very slowly from the blood by the kidneys.Most people with macroamylasemia have no serious underlying disorder, but the condition has been associated with:Celiac diseaseLymphomaHIV infectionMonoclonal gammopathyRheumatoid arthritisUlcerative colitisSymptomsMacroamylasemia does not cause symptoms.Signs and testsA blood test will show high levels of amylase. However, macroamylasemia can be confused with acute pancreatitis, which also causes high levels of amylase in the blood.Macroamylasemia can be diagnosed by measuring amylase levels in the urine. Urine levels of amylase are low. (Urine amylase levels are high in patients with acute pancreatitis.)ReferencesOwyang C. Pancreatitis. In: Goldman L, Ausiello D, eds. Cecil Medicine. 23rd ed. Philadelphia, Pa: Saunders Elsevier; 2007:chap 147.
How does saliva alpha amylase work?
Amylase is an enzyme that induces hydrolysis of starches, breaking them down into sugar. Saliva alpha amylase is simply a type of amylase.
What macromolecules are targeted amylase?
Carbohydrates are targeted by amylase.
What type of compound and bond is hydrolized by the alpha amylase?
Alpha bonds are hydrolised by alpha amylase. The alpha amylase is the sole form of amylase found in all mammals.
Why is amylase testing performed?
Amylase testing is performed to diagnose a number of diseases that elevate amylase levels. Pancreatitis, for example, is the most common reason for a high amylase level.
