Abstract
Disclosed are devices, arrangements and methods for quantifying the concentration of an analyte present in bodily fluid, including: an assay pad having at least one chemical reagent capable of producing a detectable signal in the form of a reaction spot upon reaction with the analyte; a light source; a detector array; a processor; and a memory in communication with the processor, the memory comprising: (a) at least one value indicative of one or more of: (i) the level of hematocrit contained in the sample; (ii) the volume of the sample applied to the assay pad; or (iii) imperfections present in the reaction spot; and (b) at least one algorithm for calculating the concentration of the analyte contained in the sample.

28. An arrangement for measuring the concentration of an analyte contained in
a sample of body fluid, the arrangement comprising: -
an assay pad comprising at least one chemical reagent capable of producing a detectable signal in the form of a color change at a reaction spot formed upon reaction with the analyte; a light source; a detector array; a processor; and a memory in communication with the processor, the memory comprising; (a) at least one value derived from the color change at the reaction spot indicative of one or more of; (i) the level of hematocrit contained in the sample; (ii) the volume of the sample applied to the assay pad;
or(iii) imperfections present in the reaction spot; and (b) at least one algorithm for calculating the concentration of the analyte contained in the sample. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 50, 54)
