Abstract

A device and method for testing for Cystic Fibrosis includes a sample cell having a capillary tube with a lumen that will hold approximately five microliters of sweat. The capillary tube has metallic rings around each end of the tube with an RF oscillator attached to one ring and a microprocessor attached to the other. An RF signal, which is transmitted from the RF oscillator through the sweat in the sample cell, is subsequently analyzed at the microprocessor by comparing the transmitted signal to a reference. In accordance with the comparison made by the microprocessor, the presence of Cystic Fibrosis may be detected.
