To my understanding, depending on what CGM device your patient is using, other sites other than the back of the arm can be used. For example, with Dexcom, the abdomen and upper buttocks (for ages 2-17) have been approved as reliable, tested sites for CGM placement. For isCGMs such as the Libre, the only placement approved is the back of the arm because this is where the sensor has been tested. Using this sensor in other places, such as the abdomen, would be considered “off label use”
I personally do not have patients who use their CGM sensors on “off label” placement locations, but I am curious to hear other’s feedback regarding this!
I have a client who has applied to his abdomen because he could not keep a sensor on his arm (kept bumping it off and was truly ready to give up).
I advised him that it was not a validated site but that he could do BG comparisons compare if he wished to try.
Client was consistent for 2 weeks to compare regularly and was very happy with comparable results. He now wears continuously on his abdomen.
