Method and device for performing colorimetric analysis of a test fluid to evaluate physiological parameters

A calorimetric device for performing colorimetric analysis of a test fluid to evaluate associated physiological parameters, said device comprising:

• an image capturing device configured to capture one or more images of a test strip;
• a processor coupled with the image capturing device;
• and
• a memory disposed in communication with the processor for storing processor-executable instructions, the instructions comprising instructions to:
• receive a first image of the test strip captured by the image capturing device at a first height before dipping the test strip into the test fluid, and a second image of the test strip captured at a second height after dipping the test strip into the test fluid;
• determine a plurality of first and second geometric parameters respectively associated with the test strip based on analysis of the captured first and second image;
• derive an image resizing factor based on the plurality of first and second geometric parameters and generating one of a resized first image and a resized second image based on the image resizing factor thus derived;
• determine a first and second calorimetric value respectively associated with the resized first and the resized second image;
• and
• evaluate one or more physiological parameters associated with the test fluid based on change in luminosity determined based on the one or more predetermined calorimetric values, the one or more first and the second calorimetric values.
