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 else can I help you with?
What enzyme dissolves starch?
Amylase is the enzyme that breaks down starch into maltose, a type of sugar. It is found in saliva in the mouth and in the pancreas.
Is amylase a protein?
Yes, amylase is a protein.
What happens when you heat up starch and amylase?
Heating up starch and amylase can lead to denaturation of the amylase enzyme, causing it to lose its shape and function. This can result in a decreased ability of amylase to break down starch into smaller sugar molecules.
What are the uses of starch in amylase determination?
Starch is used in amylase determination as a substrate to measure the activity of the enzyme amylase. The enzyme amylase breaks down starch into simpler sugars, and by monitoring this process, the activity of amylase can be quantified. Starch provides a standardized substrate for conducting experiments to accurately measure the enzyme's activity.
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.
How do you calculate 24 hour urine amylase?
To calculate 24-hour urine amylase, first collect all urine produced over a 24-hour period in a clean container. Measure the total volume of urine collected and then determine the concentration of amylase in a sample of this urine, typically using an enzymatic assay. Multiply the concentration of amylase (units per liter) by the total volume of urine collected (in liters) to obtain the total amount of amylase excreted in 24 hours, expressed in units.
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 is amlase?
Amylase is an enzyme that helps break down carbohydrates, specifically starches, into simpler sugars like maltose and glucose. It is produced primarily in the salivary glands and the pancreas, playing a crucial role in digestion. There are two main types of amylase: salivary amylase (or ptyalin), which starts the digestion process in the mouth, and pancreatic amylase, which continues the process in the small intestine. Amylase levels can be measured in blood or urine for diagnostic purposes, particularly in conditions related to the pancreas.
Is ptylin an alpha amylase or beta amylase?
Ptyalin is an alpha-amylase. It is the alpha-amylase found in saliva
How many kinds of amylase?
There are three main types of amylase: salivary amylase, pancreatic amylase, and fungal amylase. Salivary amylase is produced in the mouth, while pancreatic amylase is produced in the pancreas. Fungal amylase is produced by fungi and is often used in commercial applications such as in the food industry.
What enzyme dissolves starch?
Amylase is the enzyme that breaks down starch into maltose, a type of sugar. It is found in saliva in the mouth and in the pancreas.

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.

What Enzymes are responsible for breakdown of starches?
They are Broken down by Amylase Enymes.
Is amylase a protein?
Yes, amylase is a protein.
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.
