Frequently Asked Questions

What is the KS3 CKM System and who should use it?

The KS3 Continuous Ketone Monitoring (CKM) System is designed to measure ketone levels in the interstitial fluid of adults aged 18 and older. It helps users track ketone trends in real-time using a wearable sensor and mobile app. This system is not intended for diagnosing, treating, or monitoring medical conditions, and should not be used by individuals with extensive skin issues or implanted medical devices.

Is this system suitable for children or medical treatment?

No. The KS3 CKM System is only for individuals aged 18 and older and should not be used for medical decisions or disease management.

How Does the KS3 CKM System Work?


A wearable sensor continuously measures ketone levels in interstitial fluid and sends updates to the SiBio CKM App via Bluetooth every 5 minutes.

Where and how should I apply the sensor for best results?

Apply the sensor to the back of your upper arm, choosing a clean, flat area that does not bend often during daily movement. Avoid scars, tattoos, moles, stretch marks, skin folds, or irritated skin.  

Before applying, wash the area with soap and water, dry it thoroughly, then wipe it with alcohol and allow it to air-dry completely. Avoid lotions or oils, and rotate application sites between sensors to help protect your skin.

For a complete step-by-step application guide, please visit our How It Works page 

How long can I wear the sensor and what might affect its lifespan?

Each sensor is designed to last up to 14 days. However, heavy sweating, intense exercise, or improper skin preparation can cause the sensor to loosen prematurely. If the sensor becomes detached or the tip comes out of the skin, discard it and apply a new one.

Is the sensor waterproof, and what activities are allowed?

Yes. The sensor has an IP38 water resistance rating, meaning it can be submerged up to 1 meter for up to 1 hour. You can wear it while showering or swimming but avoid direct high-pressure water and prolonged submersion.

What should I do if pairing fails or the app can’t detect the sensor?

First, ensure Bluetooth is turned on and your phone is within 10 meters of the sensor with no major obstacles. If pairing still fails, restart the app and try again. If the issue persists, contact us at support@sibiosensor.com

Can I view or export historical ketone data?

Yes. Historical data is displayed in the app. If your app version supports data export, you can find this option in the “My Sensors” section under “Data Details.”

What after-sales protection does SiBio offer?

Shop with confidence. Your SiBio CKM sensor is backed by a 14-Day Quality Guarantee: eligible quality issues may qualify for a free replacement or refund. We also offer support for eligible sensor detachment and other non-quality concerns, with our dedicated team here to help throughout your experience.View Our Full After-Sales Policy

Is the sensor suitable for air travel?

Yes. However, remove it before undergoing security procedures involving strong electromagnetic fields such as MRI, CT, or X-rays.

Can I swim or bathe every day while wearing the sensor?

Yes, within limits. Avoid prolonged submersion or strong water jets.
