Advanced urine analysis
Monitor your urine calcium levels to identify a key contributing factor in kidney stone formation, since excess calcium can sometimes crystallize and contribute to stone growth.

Revolutionary U-Scan Calci to unlocks key biomarkers to form a single-purpose kidney management device.
These measurements provide the clinical data needed to manage modifiable stone formation factors.
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.
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.
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.
U-Scan Calci offers two starter-kit options, Intensive and Proactive, matched to your stone-risk profile.
Designed to blend effortlessly into your bathroom.
