Claim 14:
15. A method for generating a module configured to determine concentration of an analyte in a sample of a body fluid, the method comprising:
(a) providing one or more test strips having a region configured to change color in reaction to an analyte contained in a body fluid sample;
(b) using a plurality of mobile devices to obtain a first set of images of the one or more test strips in sequence beginning before the body fluid sample is applied to the test strip and ending after completion of the color change reaction, wherein at least some cameras, software and/or hardware device configurations for image recording and image data processing are different among the plurality of mobile devices;
(c) repeating steps (a) and (b) for a plurality of body fluid samples having different analyte concentrations;
(d) extracting image data from the first set of images for a reaction region of the one or more test strips where the color change reaction occurs and for a blank region of the one or more test strips where no color change reaction occurs;
(e) using the extracted image data to construct and train a neural network model;
(f) generating a module from the neural network model that is adapted to be loaded on a data processor;
wherein, the module is configured to determine concentration of an analyte in a second sample of a body fluid from analyzing a second set of measurement data indicative of second color information derived from images for a region of interest of one or more test strips, the images being indicative of a color transformation of the region of interest in response to applying the second sample of the body fluid containing the analyte to the region of interest.
