ABSTRACT:
A device for use in a medical diagnostic apparatus includes an area for containing a sample of biological fluid as it undergoes a reaction that causes a detectable change in the sample's optical properties. The reaction area is sandwiched between a transparent front layer and a Fresnel reflector layer. The area is illuminated through the front layer, and the light is reflected from the reflector layer to a detector. The detector monitors the light incident on it and calculates, from the change during the course of the reaction, an analyte concentration or property of the fluid sample. The reaction area is optionally heated.
