This test measures the amount of salt (sodium and chloride) in the sweat to determine whether a child has CF. Normally, sweat has very little sodium and chloride in it. In Cystic Fibrosis there is 2-5 times the normal amount of these chemicals in the sweat. The test is done in two steps. In the first step, a colorless, odorless chemical (known to cause sweating) is applied to two small areas. The sweat test measures the amount of chloride in sweat and kids with CF have very high levels and can lose excessive amounts of salt in their sweat making them prone to severe salt and water loss as well. How is it done? No special preparation is needed before the test and your child can eat, drink and have any medications they normally need. There are no needles in this procedure. The test. (1) Background: Diagnostic testing for cystic fibrosis (CF) is based on a sweat chloride test (SCT) considering the appropriate signs and symptoms of the disease and results of a gene mutation analysis.
