The Amylase test contains 1 test with 1 biomarker.
Description: Amylase is a blood test that is used to measure the amount of amylase in the blood’s serum. It is used to assess for and detect a pancreatic disorder.
Also Known As: Amy Test
Collection Method: Blood Draw
Specimen Type: Serum
Test Preparation: No preparation required
When is an Amylase test ordered?
When a person displays symptoms of a pancreatic disease, a blood amylase test may be conducted.
- Abdominal or back pain that is severe
- Appetite loss.
A urine amylase test may be requested in conjunction with or after a blood amylase test. A health practitioner may conduct one or both of these tests on a regular basis to evaluate the success of treatment and see whether amylase levels are increasing or decreasing over time.
What does an Amylase blood test check for?
Amylase is one of numerous pancreatic enzymes that aid in carbohydrate digestion. This test detects the presence of amylase in the blood.
Amylase is produced from the pancreas into the duodenum, the first region of the small intestine, where it aids in the digestion of carbohydrates. Other organs, including the salivary glands, generate it as well.
Amylase is normally found in modest amounts in the blood and urine. Increased levels of amylase are released into the blood when pancreatic cells are harmed, as in pancreatitis, or when the pancreatic duct is obstructed by a gallstone or, in rare situations, a pancreatic tumor. This raises amylase levels in the blood.
Lab tests often ordered with an Amylase test:
Conditions where an Amylase test is recommended:
- Cystic Fibrosis
- Pancreatic Cancer
- Pancreatic Diseases
How does my health care provider use an Amylase test?
An amylase test is used to identify and track acute pancreatitis. It's frequently ordered in conjunction with a lipase test. It can also be used to detect and track chronic pancreatitis and other pancreas-related conditions.
A urine amylase test may be requested as well. Its level will usually correspond to blood amylase concentrations, but the rise and decrease will occur later. A urine creatinine clearance test may be ordered in conjunction with a urine amylase test to determine the ratio of amylase to creatinine filtered by the kidneys. Because poor kidney function might result in a decreased rate of amylase clearance, this ratio is used to assess renal function.
An amylase test on peritoneal fluid may be used to assist diagnose pancreatitis in some instances, such as when there is a buildup of fluid in the abdomen.
Amylase tests are often used to track the progress of pancreatic cancer treatment and after gallstone resection that has resulted in gallbladder attacks.
What do my Amylase test results mean?
A high level of amylase in the blood may suggest the presence of a pancreas problem.
Amylase levels in the blood often rise to 4 to 6 times higher than the highest reference value, also known as the upper limit of normal, in acute pancreatitis. The increase happens within 4 to 8 hours following a pancreas damage and usually lasts until the cause is effectively treated. In a few days, the amylase levels will return to normal.
Amylase levels in chronic pancreatitis are initially fairly increased, although they frequently decline over time as the pancreas deteriorates. Returning to normal levels may not signal that the source of damage has been rectified in this scenario. The size of the amylase rise does not indicate the severity of pancreatic illness.
Amylase levels may also be elevated in persons who have pancreatic duct obstruction or pancreatic cancer.
Urine amylase levels rise in lockstep with blood amylase levels and remain elevated for several days after blood levels have returned to normal.
A high amount of amylase in the peritoneal fluid can indicate acute pancreatitis, but it can also indicate other abdominal problems including a clogged intestine or poor blood supply to the intestines.
A low amylase level in the blood and urine of a person with pancreatitis symptoms could indicate that the amylase-producing cells in the pancreas have been permanently damaged. Reduced levels can also be caused by renal illness or pregnancy toxemia.
Increased blood amylase levels along with normal to low urine amylase levels could indicate the presence of a macroamylase, a harmless compound of amylase and other proteins that builds up in the bloodstream.
