Dexcom G4® PLATINUM Continuous Glucose Monitoring | AMSL Diabetes

Dexcom G4 Platinum®

Say hello to Dexcom G4® PLATINUM. 

The Dexcom G4 PLATINUM continuous glucose monitoring (CGM) system measures your interstitial glucose levels 24 hours a day to reveal a complete view of glucose highs, lows and rates of change over time. Unlike finger sticks that give a number for a single point in time, CGM provides dynamic glucose information by showing you, every 5 minutes, where your glucose is, where it’s going and how fast it’s getting there.

The CGM Subsidised Initiative is here!

The Australian Government is now providing access to fully subsidised continuous glucose monitoring (CGM) products through the National Diabetes Services Scheme (NDSS). Subsidised access to Dexcom G5 Mobile and Dexcom G4 PLATINUM CGM sensors and transmitters is available through the NDSS to individuals, living with type 1 diabetes, who meet specific criteria. Visit for more information today or visit our CGM Subsidy Initiative page for more information on your Dexcom options.


Customised alarms.

Set your blood glucose target range to alert when you go high or low and even customise alarm tones and melodies to suit your needs. The Dexcom G4 PLATINUM has a fixed hypo alert at 3.1mmol/l to give you added peace of mind even while you’re sleeping.

Tiny sensor needle.

The sensor introducer needle has a gauge of 26G and a length of 14.6mm. The Dexcom G4 PLATINUM is approved for sensor placement on either the abdomen area or upper gluteus area for paediatric users.1

6 metre transmission range.

The Dexcom G4 PLATINUM receiver and transmitter have a transmission range of up to 6m for flexibility and convenience. The Animas Vibe insulin pump and the transmitter have a range of 3.6m.

Colour Screen.

View your glucose trends in vivid hues of yellow, red, and white on the receiver and you’ll see quickly and easily when you’re going high, low, or good to go. The Vibe insulin pump also comes with a colour screen.

Sleek Profile.

At less than 1.27cm thick, the Dexcom G4 PLATINUM receiver is sleek and small and slips easily into your pocket or purse. It’s designed to fit any busy lifestyle.

How it works

The Dexcom G4 PLATINUM CGM system can be used as a standalone system or with the Animas Vibe insulin pump. Here’s how it works:

  1. A tiny sensor is placed under the skin in a similar way to an infusion site and is worn up to 7 days at a time. After you have been trained under the supervision of your healthcare professional and AMSL Diabetes representative, you can do this on your own.
  2. The Dexcom G4 PLATINUM transmitter is then attached to the sensor.
  3. Once the sensor is inserted and the transmitter is attached there is a two hour start-up period where no information will be displayed. After this time, you will need to enter two finger stick readings from your blood glucose meter to calibrate the Dexcom system.
  4. The glucose sensor will then continuously measure your interstitial glucose levels (in the fluid space between the cells) and through the transmitter, will send information wirelessly to either your Dexcom Receiver or your Animas Vibe insulin pump.
  5. After the two initial calibrations, further calibrations are required every 12 hours.

NOTE: Video footage shows Dexcom G4 PLATINUM  in mg/dl. Dexcom G4 PLATINUM only available in mmol/L in Australia.  Receiver only available in black.

Frequently Asked Questions

What is the sensor adhesive made of?

It is a pressure sensitive acrylic adhesive coated on top of a polyester spun lace fabric. The housing is attached with cyanoacrylate glue from Loctite. Both are medical grade materials. There is no latex or bovine components in the adhesive.

How accurate is the Sensor?

Your sensor glucose readings are meant to be used for trending only. Your blood glucose meter and sensor measure your glucose from two different types of body fluids: blood and interstitial fluid. Therefore, the values from your blood glucose meter and sensor may not match exactly.  For finger stick BG values below 4.44mmol/L, the CGM reading may be up to 1.11mol/L different and still be considered accurate. For finger stick BG values at or above 4.44mol/L, the CGM reading may be up to 20% different and still be considered accurate.

How long does it take to completely charge the receiver?

You can charge the receiver two ways:

1.) First, you can use the Dexcom AC outlet charger, which will fully charge the receiver in three (3) hours

2.) Second, you can use the Dexcom USB charger, which will fully charge the receiver in five (5) hours. To use the USB charger, a Windows-compatible computer is needed and the Dexcom Studio Software must be downloaded in order to charge your receiver from a computer. After downloading the software:

a.) Plug the included USB cable into your computer.
b.) Plug other end of the USB cable into the receiver.
c.) The battery charging screen will appear on the receiver.

Note: If your receiver does not show the charging icon when plugged into the charger make sure that both ends of the USB cable are fully inserted into the receiver port and wall charger.

How long does the transmitter last?

The Transmitter battery will last at least six (6) months. However, once you see the transmitter low battery screen, replace the transmitter as soon as possible. Your transmitter battery may drain as quickly as one week or less after this alert appears. The Transmitter has  a warranty of 6 months.

Why are Profiles a good feature of the Dexcom Standalone system?

Profiles allow you to choose the way you want your alerts to behave. Depending on your daily activities, you can quickly and easily change the way your system alerts you by changing your profile settings to the sound pattern and the volume level that best fits your lifestyle needs. When you choose your profile setting it is important to know this setting will apply to all alerts, alarms, and prompts.

How do I charge the Dexcom G4 PLATINUM Receiver?

The receiver battery may be charged using one of the following options:

1. An AC power outlet
2. A Windows-compatible computer. You will need to install the Dexcom Studio Software.

How often do I need to calibrate the Dexcom CGM?

You can calibrate when you are asked for the two start-up blood sugars and when prompted by the 12-hour calibration prompt.

Where do I get access to a Dexcom G4 Platinum Full Tutorial?

Visit our YouTube page for Dexcom demonstration videos.

How does Dexcom measure your blood glucose?

The sensor continuously measures glucose in the interstitial fluid (the fluid space between the cells) and can provide data up to 288 times in a 24 hour period.

How long can I wear a sensor for?

A single sensor is approved for 7 days use – the longest wear CGM in Australia.

Do I still need to take blood tests?

Yes you do. Finger stick readings should always be used for treatment decisions.

Is the device implanted permanently under the skin?

No it is not. A very fine sensor is placed under the skin.

Is it waterproof?

The Receiver is not water resistant however the Dexcom Transmitter and Sensor are water resistant up to 2.4m for 24 hours.
