ABSTRACT:
This invention provides a method for performing a simple "sweat test" with particular use in screen testing for cystic fibrosis. The method includes the use of an iontophoretic device adapted for ambulatory use which has a self-adhesive drug-impregnated electrode for the stimulation of sweat coupled with the subsequent use of a test patch device for performing the analysis of the sweat in situ. For cystic fibrosis diagnosis, the test patch is particularly adapted to determine chloride concentration in the sweat when the concentration exceeds a predetermined level.
