DexCom, headquartered in San Diego, California, is focused on developing technology for continuous glucose monitoring to improve the lives of people with diabetes. Their DexCom STS system was approved by the FDA on March 27, 2006. Since then, Dexcom has upgraded their system to the new Dexcom G4 Platinum. In February of 2014, the FDA approved a pediatric version of the G4 for children ages 2-17. The sensors may be placed in the upper buttocks or abdomen for children but parents are cautioned to not depend solely on the CGM for readings.  

Dexcom G4 Platinum

The Dexcom G4 Platinum ships with:

  • The G4 Platinum Transmitter - discreet, wireless transmission up to 20 feet, gentle adhesive
  • The G4 Platinum Receiver - 4" x 1.8" x 0.5", color screen, new shape, stores 30 days of data, data is downloadable to a computer
  • USB charging cable and charger
  • receiver carry case/belt clip
  • Dexcom Studio Software
  • User's Guide
  • Tutorial Disc

The sensors have a tiny flexible wire sensor that goes under the skin. The sensor fits inside a 26 gauge needle within an easy to use, disposable applicator. The design of the applicator allows nearly painless insertion of the needle in which the applicator also withdraws, leaving the wire sensor under the skin. Sensors are sold separately, in packs of 4, from the monitor. The design of the applicator allows nearly painless insertion of the needle which the applicator also withdraws, leaving the wire sensor under the skin. The G4 platinum sensors and receivers do not work with the Dexcom Seven versions.

Additional features:

  • Trends are now shown in hues of yellow, red, and white, you'll be able to quickly distinguish between highs, lows, or good readings
  • Custom tones and melodies now available for high or low alerts
  • receivers now come in Classic Black, Tickled Pink and Ocean Blue

Dexcom is working with various insulin pump companies to eliminate their receiver by moving the display into the pumps. For pump wearers, this eliminates the readout device but still requires two skin sites, one for the glucose sensor and another for insulin delivery.

Dexcom Studio

Dexcom Studio is the new software for viewing and analyzing the readings gathered from your Dexcom receiver. Hook your receiver to your computer via USB. Dexcom Studio will launch and pull off all the new readings. The receiver can hold up to 30 days of sensor data. Once it is full, the oldest records will be deleted to make room for new readings. You should plan to upload your data every 2-3 weeks. This will allow for all the sensor glucose readings to be included in the charts/reports, and will keep these data records from being lost. Dexcom Studio is not currently compatible with Windows 8.

Dexcom Studio features include:

  • Dexcom Portrait Report -Summary statistics of overall glucose control with clinical assessment notes.
  • Hourly stats - All-in-one report to easily assess glycemic patterns and variability at the same time.
  • Daily trends - Overlapping days to assess glycemic patterns.
  • Glucose Distribution - Shows percent time high, low and in target glucose ranges and overall glucose distribution. Assess pre- and post-prandial control by comparing pie chart distribution.
  • Glucose Trends - Report to review daily glucose trends, event markers and correlation between SMBG and CGM. Daily Strip Print feature prints daily glucose trends with a touch of a button.
  • Daily Stats - Review percent time spent high, low and in target glucose ranges by day.
  • Success Reports - Compares glycemic control weekly, monthly or quarterly.
Dexcom Share Cradle

Dexcom Share

The Nightscout Project has shown us how data availibility is possible. Dexcom has taken a step in that direction finally receiving FDA approval for the Dexcom Share in October 2014. Dexcom showed the device at the 2013 AADE meeting. Since it was not yet FDA approved, no one was able to actually use the device but people were at least able to see it. According to the Diabetesmine, Dexcom submitted to the FDA way back in July of 2013.

The Share is a cradle like device that you plug your Dexcom receiver into. The cradle must be plugged into an electrical outlet at all times. The cradle uses Bluetooth to transmit your data to the Dexcom Share App on your iPhone (4S or later) or iPod touch (5th generation or later). You may only pair one device with the cradle at a time and the system is not yet available with Android phones. Your readings are  then sent to the cloud so other devices may access the data, with your permission, using the Dexcom Follow App. The share app has to be running in the foreground or background to receive data. You are able to invite up to 5 other people to receive CGM data from your Share. This is a great help to parents, partners, or physicians of people with diabetes. The received data is completely programmable, allowing the receivers to choose exactly which information they would like to be notified about. 

The Share is currently sold for $299. You do not need a prescription but insurance companies are not yet covering the device so expect to pay out of pocket. Take a look at the Dexcom Share FAQ for more info.
