Withings U-Scan

Welcome to a new era for urinalysis

With more than 3000 metabolites, urine is an extraordinary witness to our health. It gives an immediate snapshot of the body’s balance and can help detect and monitor a large variety of health information. While urinalysis is typically performed only once a year, U-Scan opens the door to regular access to these metrics from the comfort and privacy of one’s own bathroom.


Data capture made easy

U-Scan is a technologically advanced pebble-shaped reader and interchangeable analysis cartridges designed to assess specific biomarkers without the need for external sample capture or strips. The data capture is noninvasive, effortless, hands-free and automatic. Each cartridge lasts three months and can easily be changed to meet all your needs.

Multiple Biomarker Analyses

Each cartridge is made of a dozen test pods containing specific types of biomarker tests. When placed in the reader, this versatile system can support nearly limitless medical and health use cases simply by adapting the test pods.

What is U-Scan?

U-Scan is a new product category at Withings which aims to unlock the wealth of health information to be found via regular at-home urine analysis. It is a versatile cartridge-based platform able to detect, measure, and analyze multiple biomarkers in urine.

Is U-Scan a medical device?

The U-Scan Nutri Balance and Cycle Sync cartridges are not medical devices, both are intended to encourage and/or help the user maintain a healthy lifestyle.

What is the U-Scan Cycle Sync cartridge intended for?

U-Scan Cycle Sync is the first and the only automatic hormonal-based cycle tracking solution, providing effortless, accurate, and hygienic urine testing. Personalized insights will help a woman build a cycle-adapted health routine without the mental load that accompanies most menstrual tracking. U-Scan Cycle Sync enables the detection of the following biomarkers:

  • LH (Luteinizing Hormone) for precise menstrual cycle prediction & ovulation window determination
  • Specific gravity for water balance
  • pH for protein-vegetable balance
  • Can I use U-Scan Cycle sync?

    U-Scan Cycle Sync is currently suitable for women who, within the last three months, have met the following criteria:

  • Menstrual cycle is between 21—35 days
  • Not under the age of 18
  • Not on hormonal treatment such as birth control, fertility treatment or hormonal therapy
  • Not diagnosed with PCOS (polycystic ovary syndrome)
  • Not currently or recently pregnant (in the last 3 months)
  • Not breastfeeding / have not breastfed recently (in the last 3 months)
  • Not experiencing menopausal symptoms (such as hot flashes)
  • What is the U-Scan Nutri Balance intended for?

    U-Scan Nutri Balance is the first solution able to seamlessly test several key biomarkers for hydration and nutrition via hygienic and automatic urine analysis, combined with an in-app coaching experience to improve overall daily health. U-Scan Nutri Balance enables the detection of the following biomarkers:

  • Specific gravity for water balance
  • pH for protein-vegetable balance
  • Ketones for energy metabolism
  • Vitamin C levels
  • Can I use U-Scan Nutri Balance?

    U-Scan Nutri Balance is made for anyone who is looking to balance their nutritional health by analyzing key biomarkers alongside expert-reviewed and actionable insights (workouts, recipes, tips) to achieve their goals.
    Because urine biomarker reference ranges are very different for babies, children and teens, we don’t recommend that people under 18 use the Nutri Balance cartridge.

    When will U-Scan be available?

    U-Scan will first be made available in Europe starting in the end of 2023 with Nutri Balance.

    What is U-Scan for professionals?

    Withings Health Solutions, the company’s division serving the professional health market, is making the device available to partners for research and tailored use case purposes to extend the possibilities offered by the U-Scan platform. U-Scan for Professionals pricing is upon request, please contact our Health Solutions team via this link.

    How accurate is U-Scan?

    Performance has been validated by a third-party lab accuracy study.

    What are the technical features (size / weight / components) of U-Scan?

    U-Scan is composed of 2 parts:

  • The Reader: This technologically advanced pebble-shaped device contains all the components required for urine sample collection, analysis by optical means, and data transfer by Bluetooth or Wi-Fi connection. Reader dimensions are ⌀ 90 x 28.5 mm, and the weight is 110 grams
  • The Cartridge: This interchangeable component is a cylindrical plastic part inserted in the Withings U-Scan Reader which contains dozens of test pods composed of chemical reagents which can detect the level of various human biomarkers in urine. Cartridge dimensions are ⌀ 62.55 x 15 mm, and weight is 15 grams
  • How long does the U-Scan battery last?

    The U-Scan battery is designed to last for up to 3 months, and each cartridge is also designed to last for 3 months.

    Is my toilet compatible with U-Scan?

    U-Scan is designed to be compatible with most Western-style toilets. The device can be mounted within the toilet bowl thanks to an included fixation arm. The product includes several fixation arm sizes making it able to adapt to most toilet shapes.

    How does the U-Scan device stay clean within the toilet?

    U-Scan was specifically designed to live in the toilet environment.
    When closed, the product is splash and water resistant, urine or toilet pollutants cannot penetrate to the inside.
    U-Scan is made with a glass-fiber reinforced material that can resist the toilet environment.
    The product's surface is designed to be rinsed with each toilet flush, just like the ceramic of the toilet bowl.

    How much does U-Scan cost?

    Users will be able to buy U-Scan starter kit for €499.95 to get one U-Scan reader and one cartridge (Cycle Sync or Nutri Balance) that provides 3 months of testing. Users will then have a choice to subscribe to automatic refills (€29.95 monthly subscription) or buy standalone cartridges on withings.com. U-Scan for Professionals pricing is upon request, please contact our Health Solutions team via this link..

    How do you change your cartridge or charge the device?

    If already installed, you simply remove U-Scan from your toilet via the fixation arm and follow cleansing instructions.
    Open the device by unscrewing the front case to access the inside of the product. Remove the cartridge if already inserted, and insert the new cartridge. Then go to the Withings Health Mate App to follow the installation procedure.
    While open, plug the USB-C charging cable to the reader’s port and a power source. Once charged, remove the charging cable and close up the front case.

    How many biomarkers can be analyzed in a cartridge?

    Each cartridge includes more than 100 biomarker results, which is designed to provide 3 months of testing when following the recommended measurement plan in the Withings App.
