sweat test
Quick Summary
The sweat test is a medical diagnostic tool used to identify cystic fibrosis. This test measures the concentration of sodium chloride in a person's sweat. Individuals with cystic fibrosis exhibit abnormally high levels of sodium chloride in their perspiration.1
Chlorine, a component of sodium chloride (salt), is vital for various bodily functions, including maintaining fluid balance and acid-base equilibrium. It is present in all body secretions and is excreted through sweat, kidneys, and the intestines. Excessive sweating, particularly in hot weather, can lead to a depletion of the body's chlorine levels.2
