Introduction: A smartphone offers portability, convenience, and cost savings—attributes that can extend to the use of analytical systems, consequently helping users measure analytes when they do not have access to the necessary tools for standardized measurement, in addition to the ability to carry out and conduct analysis anywhere. Objective: To determine whether image analysis performed through a smartphone is valid or verifiable for the measurement of serum glucose compared to the spectrophotometric method. Material and Methods: A non-experimental longitudinal study was designed at the Guadalupe clinic during the period of October–February 2024. Serum concentrations ranging from 30 to 500 mg/dL were evaluated using the spectrophotometric method and also through image analysis with a smartphone. Results: Decreasing concentrations were evaluated starting from 500 mg/dL, where the smartphone image capture method showed linearity from 50 mg/dL. Regarding accuracy, no significant differences were found between both methods. The coefficient of variation was also calculated for high (455 mg/dL), medium (200 mg/dL), and low (35.64 mg/dL) concentrations, inferring good precision for medium and high concentrations. As for the detection limit, the image-based method was found to have a lower detection limit than the spectrophotometric method. Conclusion: It is concluded that image analysis has good performance in concentrations ranging from 50 mg/dL to 500 mg/dL in relation to the spectrophotometric method.
