Evaluation of Traceability of Dietary Urine Biochemistry Changes with Commercial Urine Strips

Abstract

Objective: This research aims to (i) examine the effects of nutrition on urine biochemistry and (ii) compare the two different measurement methods (laboratory and commercial strip). This means it is desired to bring a new direction to the literature. Methods: The study involved 42 women aged 20-30 from Turkey and examined the urinary excretion of calcium, vitamin C (smoker and non-smoker), sodium, and magnesium based on nutritional status. The collected urine samples were applied onto commercial urine strips, and the resulting color changes were recorded by smartphone; at the same time, it was sent to the laboratory for comparative analysis. The obtained data were used in regression and correlation statistical analysis. All statistical analyzes were performed using IBM SPSS 28.0. Results: While evaluating the regression analysis results in which the excretion due to nutrition was examined, each nutritional level was compared to the restricted intake. ANOVA sig values
