Buy Dexcom ONE+ Sensor - Single

The Dexcom ONE+ features an all-in-one sensor and transmitter that automatically sends glucose readings to a receiver or compatible smartphone. The sensor is preloaded in the applicator and can be inserted with the push of a button. 

Once inserted, it can be worn for up to 10 days. Dexcom ONE+ is compatible with the latest Apple iPhones and many popular Android devices. Please check if your smart device is compatible with Dexcom ONE+ here.

 

Directions

You will use an applicator to insert a small sensor wire under your skin, which is held in place by an adhesive patch. The sensor can be worn on your arm, abdomen, or upper buttocks (children ages 2-6). It continuously measures glucose levels in the interstitial fluid around the clock. 

Every 5 minutes, the sensor wirelessly sends a glucose reading to your compatible smart device or receiver. This allows you to view your current glucose levels in real-time and your historical trends.

The Dexcom ONE+ app and receiver can also be configured to send custom alerts when specific glucose thresholds are reached. For more information on how to use Dexcom ONE+, please refer to the manufacturer's website.

 

Warnings

To ensure safe use of the Dexcom ONE+ Continuous Glucose Monitoring System, follow all instructions, including indications, contraindications, warnings, precautions, and cautions. 

Improper use may result in missing a severe hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose) event or making a treatment decision that could cause injury. 

If Dexcom ONE+ glucose alerts and readings do not match your symptoms or expectations, use a fingerstick blood glucose reading from your meter for diabetes treatment decisions. Seek medical attention as needed.

Review the product instructions before using Dexcom ONE+. Important user information is available on the Dexcom website and in the product instructions.
