Amylase is a kind of enzyme found in the pleural fluid between the lungs and the chest cavity. It is a special enzyme produced by the pancreas for the purpose of food breakdown in the cells. When there is damage or a kind of inflammation in the pancreas, then there is excessive production of this enzyme. The Amylase test is used to detect this problem. It evaluates the problems in the pancreas and diagnoses any issues in the oesophagus as well. It is conducted as a routine blood and urine test. The results are measured at the laboratory.
