Researchers have identified components of sweat that might help diagnose babies with cystic fibrosis, according to the American Chemical Society.
The researchers profiled the chemical composition of sweat from screen-positive infants including both unaffected carriers and confirmed CF cases. They identified several unknown chemicals in sweat that were consistently associated in babies who had CF, in addition to chloride. The researchers suggest that testing for these alternative molecules could be done for cases in which the chloride sweat test is too close to call. They also intend to track the progression of CF and monitor treatment responses to therapy in children using these and other sweat molecules.
