Non-invasive glucose monitoring devices can enormously improve patient care and management. Objective: This study aimed to develop an instrument able to non-invasively measuring blood glucose levels using an infrared transmitter and receiver, with information processing performed by a dedicated processor. Material and Methods: This analytical research develops a glucometer that incorporates a power supply, a light supply, a gentle detector, a sampler, and sign processing elements to allow non-invasive glucose measurements. The instrument was calibrated utilizing sugar answer samples with known glucose concentrations. It was then tested utilizing serum samples from diabetic patients with accuracy, which was evaluated utilizing Clarke's grid evaluation. Results: Testing of the designed glucometer revealed that 83% of the serum samples fell inside zone A of Clarke's grid analysis, indicating high accuracy. The remaining 17% of samples were categorised in zone B, with no samples falling in zones C, D, or E. Conclusion: The developed glucometer demonstrated larger accuracy in measuring glucose concentrations above 200 mg/dl. Despite the usage of serum samples on this experiment, 83% of the outcomes were positioned in zone A leads to the capability of noninvasively measuring blood glucose ranges. Further studies are required to validate the gadget's accuracy in a larger inhabitants and assess its utility in clinical observe.
