Sweat Test

h9991425_001.jpg

A sweat test is used to diagnose cystic fibrosis. During the test, medicine that causes sweating is applied with a gauze pad to either the arm or the thigh. A mild electrical current pushes the medicine into the skin to cause the child to sweat. The sweat is collected, and then the salt content of the sweat (sodium and/or chloride) is measured.
