Abstract
An improved system for monitoring blood glucose, especially in remote regions, is provided. The system includes a substrate comprising a sample umbra and a control umbra and a printer capable of printing coatings on the substrate thereby forming a printed substrate. A first coating comprises glucose oxidase and the first coating is in the sample umbra but not in the control umbra. A second coating comprises peroxidase and the second coating is in the sample umbra and the control umbra. A third coating comprises and indicator and the third coating is in the sample umbra and the control umbra. A barrier encases at least a portion of the coated substrate except for a sample window. When blood is applied to the sample window plasma of the blood wicks into the substrate, exclusive of red blood cells, such that the plasma enters the sample umbra and the control umbra. A detector is provided which is capable of measuring a color change of the indicator in the sample umbra and the control umbra.
