As one of the symptoms of cystic fibrosis is the presence of more salt in the body and on the skin; therefore, the level of sweat is higher in the people with this disease. In the test, a comically called pilocarpine is spread over the patient’s skin, then a small amount of electric stimulation is applied to encourage sweat glands to produce sweat. After sweat production, it is then collected in a plastic coil or piece of filter paper. There is no age limitation for this test. Anyone can have the test. It does not require the use of a needle and is not painful.
