Frequently Asked Questions
Four nutrition markers from your urine: Ketones (found in urine when your body starts to use fat as fuel), HydroStatus (hydration), Vitamin C (antioxidant intake), and Bio-Acidity (pH, your diet's acid balance). Each measurement comes with a reading and personalized guidance in the Withings app.
Yes. U-Scan Nutrio is designed to fit standard toilets. Installation takes about 5 minutes with the included closing tool and toilet clips (S/M/L). A quick guide is in the box, and the app walks you through it with videos and explanations.
The reader is fully water-resistant and self-cleaning, rinsing with every flush. It only samples when you start a measurement in the app. Cleansing powder and protective gloves are included for handling the cartridge.
Not for now. Each U-Scan tracks one person. The rest of the household can use the toilet as usual, their urine simply won't be analyzed.
Your first video session with a registered dietitian through Fay is included with every U-Scan Nutrio. They review your U-Scan trends alongside your goals, diet, and lifestyle, then build a plan, whether that's weight loss, a GLP-1 journey, keto, sports nutrition, or general health. Follow-ups are billed directly by Fay through your insurance; coverage varies by plan and benefits.
Yes, for most members, through a Letter of Medical Necessity (LMN). Truemed handles the LMN at checkout: you answer a short health questionnaire, and if you qualify, a licensed provider issues the letter so you can pay with pre-tax HSA/FSA dollars and save up to 30%. Eligibility is determined individually; Withings does not guarantee it.
Your membership keeps fresh cartridges arriving, plus the app tools, food insights, and expert webinars. Cartridges renew automatically with advance notice before every shipment and charge. You can pause or cancel anytime.
No. U-Scan Nutrio is a wellness product you can use on your own. It doesn't replace medical testing, and you can always share your exported report with your doctor or dietitian, using Health Link in the Withings app.
Your data is yours. It is encrypted, never sold, and shared only with the people you choose, such as your Fay dietitian or your own doctor via the report you export. Full details are in the Withings privacy policy.
