During the sweat test , medicine that causes a person to sweat is applied to the skin (usually on the arm or thigh). The sweat is then collected on a paper or a gauze pad, and the amount of salt chemicals in the paper or gauze is measured in a lab. Generally, chloride (sweat chloride) is measured.
The exact cause is not known, but could be related to an allergy to sweat itself. Sweat triggers the release of histamine causing itchiness in the legs or other parts of the body. It may also present with warm skin and small (up to 2-3 mm) bumps, which usually persist from 30 minutes to 2 hours. Some people may respond with a positive patch test to their own sweat.
