Could a simple urine test replace blood draws for electrolyte monitoring?
NCT ID NCT07704450
First seen Jul 15, 2026 · Last updated Aug 28, 2026 · Updated 3 times
Summary
This study tests a prototype device that measures electrolytes like sodium and potassium in urine. Healthy adults aged 18 to 60 will provide urine samples after eating different standardized meals (such as high-fruit or nut diets) and during their normal daily life. The goal is to see if the device can produce complete and accurate readings without errors, which could pave the way for at-home health monitoring.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a prototype urinary electrolyte monitoring device and standardized diets (fruit, nut, calcium supplement, DASH diet)
- What this could lead to
- If the device works reliably, it could lead to a simple, non-invasive way to track electrolyte levels at home, helping people manage their diet and health.
- What could go wrong
- This is a small, early feasibility study with only 40 healthy adults, so the device may not work as well in real-world conditions or in people with health issues.
