Dynamic Monitoring of Urinary Electrolytes
Starting soon · Not applicable
Conditions studied: Healthy
In brief
This interventional device feasibility study evaluates the operational feasibility of a prototype urinary electrolyte monitoring device in healthy adults aged 18 to 60 years. Urine samples will be collected during protocol-defined dietary intervention conditions and free-living conditions to determine whether the prototype device can generate complete urinary sodium, chloride, potassium, magnesium, and calcium measurement results without device malfunction, sample-processing failure, unreadable signal output, or repeat device operation. Dietary intervention conditions are used to provide physiologic variation in urinary electrolyte levels and to create testing conditions for the prototype device. The primary outcome is the valid measurement rate of the prototype device across collected urine samples. Secondary outcomes will summarize changes in urinary electrolyte levels following dietary interventions and within-participant variability under free-living conditions. Participants will provide baseline anthropometric and physiological data, including height, weight, age, and blood pressure, along with baseline fasting morning urine samples. Participants will consume assigned standardized meals or provide urine samples under free-living conditions, depending on study arm assignment. Longitudinal urine samples will be collected at protocol-defined time points, such as post-prandial intervals or other scheduled collection times during the study period.
