“Sweat Stickers” May Ease Cystic Fibrosis Diagnosis and Management

An elevated chloride concentration in an infant’s sweat is indicative of the genetic, progressive disease cystic fibrosis. A team of researchers has developed “sweat stickers,” which may streamline the early diagnosis of cystic fibrosis by enabling scientists to easily gather and analyze sweat from the skin of infants and children. The stickers matched the performance of existing, more cumbersome devices when tested with 51 subjects.
