Advanced urine analysis
The calcium connection to kidney health
Tracking your urine calcium levels may help you identify a key contributing factor in kidney stone formation, since excess calcium can sometimes crystallize and play a role in stone growth. U-Scan Calci is the first at-home urine analyzer designed to continuously monitor calcium and other nutritional markers—helping you gain better insights and make more informed choices for your kidney health.
Calcium
HydroStatus
Bio-Acidity
Revolutionary U-Scan Calci unlocks three key health parameters to help you understand your body’s unique response to the different foods you eat.
These key insights offer you actionable information to help you adopt healthier habits—and empower you to proactively manage factors known to contribute to kidney stone formation.
Track your calcium levels
70-80% of kidney stones start with excessive calcium—
observing spikes in your levels may help you adopt healthier habits and empower you to proactively manage factors known to contribute to kidney stone formation.
Regulate your Bio-Acidity levels
Through urinary pH, a key indicator of a healthy diet.
Keeping your urine’s pH above about 6 makes it less likely for uric acid to turn into tiny crystals—another kind of kidney stone. These insights help you take control of factors linked to stone formation, such as diet, hydration, and acidity levels.
Follow your HydroStatus
Small shifts may reflect changes in how much fluid your body needs.
Staying well-hydrated is an important habit for kidney health, and knowing when to adjust your water intake can help support your body’s natural defenses.
