[A new type of sweat test and its use in children].

Chloride concentration in sweat was determined by the method of Skine Chloride System of Orion's Model 417 in 100 healthy children and 42 CF children. Statistically significant differences were demonstrated in chloride concentration in sweat between the group of healthy children and CF children. The results of our investigations suggest, that this method is useful in the diagnosis of CF in childhood.
