Amylase

Description

Amylase is usually present in the blood and urine. It is produced by the pancreas, as many other enzimes, and helps digesting fats, proteins and carbohydrates. If pancreas`s cells are damaged or the pancreatic duct is closed, this enzyme increases its concentration in the blood and the urine. Amylase is produced also by salivary glands.

Amylase blood analysis is ordered when a patient has symptoms of a pancreatic problems such us abdominal pain, fever, loss of appetite, or nausea.  Also an urine amylase test may be ordered in orther to monitor the evolution of the disease with the treatment.

Its concentration is measured by means of analysis of a blood sample drawn from the vein in the arm.  Also can be meassured by an urine sample.

Purpose of the test

Amylase test measures the concentration of amylase in the blood or urine.

It helps to diagnose and monitor pancreatitis or other pancreatic problems.

Amylase tests are also used to monitor pancreas cancer treatment and after removal of gallstones on  gallbladder attacks.

Reference range values

25 – 115 U/L

Abnormal findings

High levels of blood amylase can be caused by:

·        acute pancreatitis

·        chronic pancreatitis

·        pancreatic duct obstruction

·        cancer of the pancreas

High levels of blood or urine amylase can also be caused by:

·        ovarian cancer

·        lung cancer

·        tubal pregnancy

·        mumps

·        intestinal obstruction

·        perforated

Low levels of blood and urine amylase can be caused by permanent damage to the amylase-producing cells in the pancreas.

High levels of blood amylase together with low values of urine amylase can be caused by decreased kidney.
