Understanding CGM
What is a CGM and how does it work1,2?
A Continuous Glucose Monitoring (CGM) system measures glucose levels in the interstitial fluid beneath your skin throughout the day.
A small sensor is inserted under the skin, usually on the arm or abdomen, depending on the device's approved application sites. The sensor measures interstitial glucose every few minutes and sends the information wirelessly to a compatible smartphone.
How is CGM different from finger-prick testing1–4?
A blood glucose meter (BGM) measures glucose in a drop of blood from your fingertip, while a CGM system measures glucose in the interstitial fluid beneath your skin.
Because glucose levels in blood and interstitial fluid do not change at exactly the same time, CGM readings may lag behind blood glucose readings. This difference may be more noticeable when glucose levels change rapidly, such as after meals, during exercise or following insulin administration.
Therefore, CGM and BGM readings may not always be identical, even when both devices are functioning properly.
If your CGM reading does not match how you feel, or you suspect the reading is inaccurate, check your glucose with a BGM and follow your device's instructions. If discrepancies persist, consult your healthcare professional.
Why do I need a CGM1,2?
A CGM system allows frequent glucose measurements without the need for numerous finger-prick tests. It provides a more detailed understanding of how your glucose levels fluctuate throughout the day.
CGM can help you and your healthcare professional better understand your glucose patterns and support diabetes management. Clinical evidence suggests CGM may help improve HbA1c and increase time spent within the target glucose range. It can also help identify high and low glucose episodes and reduce time spent in hypoglycaemia.
Getting Started & Daily Use
Can I apply Anytime 5 CGM myself2?

How do I choose an application site for Anytime 5 CGM2?
Anytime 5 CGM can be applied to the back of the upper arm or abdomen. For abdominal application, avoid the rib area and keep the sensor at least 2 cm away from the navel.
Follow the application instructions provided with your sensor.
How long can the CGM be worn2?
Anytime 5 CGM can be worn for up to 16 days and provides continuous glucose measurements every 3 minutes, including glucose levels, trends and alerts.
Follow the product instructions for use and replace or remove the sensor as directed.
Does Anytime 5 CGM require scanning to receive new glucose readings2?
No scanning is required. Once connected to the app, Anytime 5 CGM transmits glucose data via Bluetooth and automatically updates readings every 3 minutes.
Does Anytime 5 CGM require calibration2?
No. Anytime 5 CGM is factory-calibrated and does not require routine finger-prick calibration during use.
Can I shower or swim while wearing Anytime 5 CGM2?
Anytime 5 CGM can be worn while bathing, swimming or exercising. It is rated IP58, meaning it is dust-protected and can withstand immersion in water up to 1.5 metres for up to 1 hour under specified test conditions.
The sensor adhesive is designed to help keep Anytime 5 in place for up to 16 days. Follow the product instructions for any limitations on water exposure.
Readings & Accuracy
How accurate is the Anytime 5 CGM system2?
The reported Mean Absolute Relative Difference (MARD) for the Anytime 5 CGM system is 8.58%. The FAQ source document also reports that 99.99% of glucose readings fell within Zones A and B of the Consensus Error Grid in a clinical study.
These are study-specific performance results. CGM readings may differ from blood glucose meter readings, particularly when glucose levels change rapidly. If a reading does not match your symptoms, confirm it with a BGM and follow your device instructions.
Can temperature affect my sensor's readings2?
Anytime 5 CGM has an operating temperature range of 5°C to 40°C and a storage temperature range of 2°C to 30°C. Ensure the sensor is used and stored within the specified temperature ranges.
Why does my CGM show low readings while I am sleeping5?
Your CGM may sometimes show unexpectedly low glucose readings while you are sleeping. One possible cause is pressure on the sensor when you lie on it. This tissue compression may temporarily affect the glucose reading. This is sometimes called a “compression low.”
Important: Do not assume every low CGM reading during sleep is caused by sensor pressure. Nocturnal hypoglycaemia is also possible. Confirm the reading with a BGM, especially if the CGM reading does not match how you feel, and follow your healthcare professional's advice.
When should I confirm a CGM reading with a finger-prick test4?
Confirm your CGM reading with a finger-prick blood glucose meter (BGM) when:
- The CGM reading does not match your symptoms or how you feel.
- The sensor reading does not match your personal perception.
- You need to confirm a suspected hypoglycaemia (low blood glucose) episode.
If you have symptoms of hypoglycaemia, do not delay appropriate treatment while waiting for confirmation. Follow your healthcare professional's treatment advice.
