Drops of sweat. Sweat is a liquid that is made by the skin when the body is hot. Sweat is made in sweat glands under the surface of the skin, and it comes out of tiny holes in the skin called pores. Sweat is mostly water, but it also contains some salts. The body makes sweat to cool itself down. The sweat takes the heat from the body when it evaporates (turns to gas).
The sweat test measures the amount of chloride in the sweat. There are no needles involved in this test.
