Withings Announces U-Scan - The World’s First Hands-free Connected Home Urine Lab
Sophisticated urine analysis allows users to monitor metabolic insights and empowers women to manage
monthly cycles
Issy-les-Moulineaux – January 3, 2023 Following four years of development, Withings, global leader inconnected health is proud to announce U-Scan, a breakthrough in-home biomarker analysis platform.
One of the company’s most technologically advanced devices to date, U-Scan is a miniaturized health labthat hygienically sits within any toilet bowl1 to unlock the wealth of health information in daily urine.
U-Scan has already been recognized by the Consumer Technology Association as a CES 2023 Innovation
Award honoree in three categories: Smart Home, Fitness & Sports, and Digital Health.
With more than 3000 metabolites, urine is an extraordinary witness to assess and monitor one’s health.
It gives an immediate snapshot of the body’s balance and is integral in monitoring and detecting a large
variety of health information. While we urinate on average 7 times a day, urine analyses are usually
performed only once a year. Withings U-Scan aims to change that by making it possible in the future to
conduct biomarker assessments from the comfort and privacy of a person’s own bathroom.
A game changer in home health, U-Scan is designed to be a versatile platform consisting of atechnologically advanced pebble-shaped reader and changeable analysis cartridges designed to assess
specific biomarkers without the need for external sample capture or strips. Then, with seamless sync tothe Withings Health Mate app, it will provide a wealth of actionable insights based on daily readings.
It will debut in Europe with two consumer health cartridges with medical versions following in thefuture. These include U-Scan Cycle Sync for women’s monthly cycle tracking and syncing and U-Scan
Nutri Balance, a detailed metabolic guide to hydration and nutrition. Withings U-Scan is in developmentin the US and will not be available until it receives FDA clearance.
In addition, Withings Health Solutions, the company’s business to business division serving thehealthcare provider market, is making the technology available to partners for research purposes.
“The ability of U-Scan to perform daily urine analysis from the home will allow Withings to take its
mission to help consumers fully utilize urine data to an entirely new level,” said Mathieu Letombe,
Withings CEO. “It’s one of the most exciting and complex products we have ever announced. We begin
this journey with U-Scan Cycle Sync and Nutri Balance and look forward to announcing more cartridges
on an ongoing basis as well as medical applications of the technology.”
Easy as 1, 2, Pee - How it Works
While easy to use, U-Scan overcomes a myriad of technical and chemical challenges. Developed within-vitro diagnostic experts, it was four years in the making and resulted in 13 patent application families.
As a complete system, U-Scan performs three tasks:
1) Automated Sample Capture – using a sophisticated reader within a toilet bowl

for Western toilet bowls

Just 90 mm in diameter, the rechargeable U-Scan reader is engineered to distinguish between externalliquid and urine and automatically funnel samples for analysis. Urine flows efficiently to a collection inlet
thanks to its pebble-shaped design. A pump is activated when a thermal sensor detects the presence ofurine, which starts a sample’s fluidic journey within a microfluidic circuit.
After its collection, the urine sample is injected into a test pod where the chemical reaction is read by an
optical module. At the end of each measurement, the circuit returns to the idle position and theremaining liquid is purged through a waste outlet. The system is subsequently cleaned with every flush.
U-Scan can distinguish between various users thanks to its Stream ID feature. Low-energy radar sensorsembedded within the reader measure multiple variables to identify an individual's urine stream
signature, by detecting movement and distance of the stream. Stream ID information can be affirmed inthe app.
2) Biomarker Analyses – within a miniaturized urine lab tailored to specific use cases
The rotating cylindrical U-Scan cartridge is a tiny chemical assessment chamber containing dozens ofminiaturized test pods that can deliver reliable results.
When the reader delivers the sample to the injection point U-Scan begins the chemical analysis within
moments. It automatically Patented cartridge transmits results via Wi-Fi and then rotates the cartridge
to expose the next test pod to the injection point. Each cartridge is designed to support up to threemonths2 of readings.
The module system is purposely designed to allow Withings to continually develop and support theanalysis of biomarkers associated with various medical and health conditions. Combined withmeasurements from Withings’ ecosystem, U-Scan will create even more insights for users and is an
exciting tool to potentially help prevent diseases, improve quality of life, and reduce healthcare costs.
3) Actionable Advice – science-backed guided insights
The accompanying Withings app provides results, actionable insights, and guidance designed to help
people build habits for enhanced wellness. In Europe, the U-Scan Cycle Sync results will appear in theWithings app that becomes a central place for cycle tracking, coaching, and journaling. It will show cycle
predictions and ovulation window based on hormonal detection alongside key hydration and dietarybiomarkers, specific gravity and pH levels to help women manage every aspect of their cycle. Full
information on U-Scan Cycle Sync is available here. U-Scan Cycle Sync is under development in the USA;its features will be announced when the solution becomes available following FDA clearance in thefuture.
In Europe, the U-Scan Nutri Balance cartridge will enable analysis of specific gravity, pH, vitamin C andketone levels. It helps people monitor their metabolic intake to optimize their daily hydration andnutrients. As well as displaying results such as carb balance and pH levels, it recommends workouts,
dietary suggestions, and recipes to achieve identified goals. Full information on U-Scan Balance isavailable here. U-Scan Nutri Balance is under development in the USA; its features will be announced
when the solution becomes available following FDA marketing clearance in the future.

Availability.
U-Scan will first be available in Europe from Q2 2023 with consumer cartridges Nutri Balance and Cycle
Sync3. Users will be able to buy U-Scan starter kit for €499.95 to get one U-Scan reader and one cartridge
providing 3 months of testing; then they will be able to subscribe to an automatic refill or buy astandalone cartridge on withings.com.
Future medical cartridges of U-Scan will be available pending regulatory approvals in Europe.
U-Scan is not for sale in the United States but is in development and plans to be available in the future
following FDA clearance.
