Mucoviscidosis is rapidly detected by determining the sodium or chlorine concentration in the sweat secretions of the subject by diagnostic means comprising an absorbent support impregnated with an indicator substance for indicating sodium or chlorine ions by way of a color change and capable of producing a plainly visible color when the sodium or chlorine ion concentration is at least 50 mval/l of absorption volume, and a transparent envelope which seals in the color indicating substance on all sides of said absorbent support, and which is perforated on one flat side to permit absorption of sweat directly from the skin surface of the subject.
