CGM Approved for Use Without Finger Sticks

By Miriam E. Tucker , ,

Life just got a bit easier for people who wear the Dexcom G5 Mobile continuous glucose monitoring system: Now you can use your CGM reading to calculate your insulin dose or make decisions about treating low blood glucose, without confirming the reading. (You’ll still need to perform finger sticks twice daily to calibrate the system.) The Food and Drug Administration (FDA) decision to approve the Dexcom G5 for dosing was based on a study of 130 adults and children ages 2 and older who wore the system for seven days. The CGM values aligned well both with finger-stick tests and with blood tests done in a lab. But check with your health care provider (and be sure your device is calibrated) before adopting this practice to make sure it’s right for you.
