Purpose. Reverse iontophoresis extracts glucose across the skin in the GlucoWatch Biographer, a device to monitor glycemia in diabetes. However, the device must first be calibrated with an invasive “finger-stick” and this has been perceived as a disadvantage. Here, urea, a neutral “internal standard” is extracted simultaneously in an attempt to render the technique completely non-invasive. Methods. In a 5-h experiment in human volunteers, reverse iontophoretic fluxes of glucose and urea (Jglu… CONTINUE READING
