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.
Sweat glands are located in the dermis or deep layer of the skin, and are regulated by the temperature control centers in the brain. Sweat from the gland gets to the surface of the skin by a duct. A heat rash occurs when sweat ducts become clogged and the sweat can't get to the surface of the skin.Instead, it becomes trapped beneath the skin's surface causing a mild inflammation or rash. Heat rash is also called prickly heat or miliaria. Heat rash usually fades when the skin is allowed to cool. 2  Medical treatment is necessary only if the area becomes infected. 3  Heat rash can be prevented by avoiding hot, humid conditions, wearing lose fitting clothes and using air conditioning or fans to allow air to circulate.
