Though BGM (Blood Glucose Monitoring) and CGM (Continuous Glucose Monitoring) provide information about your glucose levels, there are some key differences:

Measuring frequency

The frequency of obtaining glucose values is different between using a BGM and CGM. Using a BGM, you might test your blood glucose levels several times a day, typically before meals and bedtime, depending on your type of diabetes and medication.
With CGM, your glucose level is measured continuously. The glucose values measured by the sensor in your skin are transmitted every 5 minutes and combined to create a glucose curve. You get a full picture of your glucose levels over the time you are wearing the sensor.

Measuring glucose levels in blood vs interstitial fluid

BGM and CGM also differ in where the glucose values are measured. BGM measures glucose in capillary blood drawn from your fingertips (or sometimes other places like the palm of your hand). The sensor of the CGM solution, in contrast, is placed in your skin, more specifically, in the fat layer below the skin (subcutaneous fat tissue). There, your glucose level is measured in the fluid between the cells (interstitial fluid, not blood).

Yes, the Accu-Chek SmartGuide CGM solution can be used during pregnancy.

Every 5 minutes, the sensor sends CGM values to mySugr Glucose Insights via Bluetooth® Low Energy technology. mySugr Glucose Insights displays the glucose values and related statistical information relevant to diabetes management, along with enabling glucose predictions and glucose pattern detection.

The CGM sensor measures glucose values in the subcutaneous tissue. Each sensor has a wear time of up to 14 days and requires initial calibration using a blood glucose meter.

mySugr app. mySugr Glucose Insights is an extension of the mySugr Logbook (mySugr app) that becomes active when you connect an Accu-Chek SmartGuide sensor.

Yes, you can use the Accu-Chek SmartGuide CGM solution while traveling. You must remember to pack a charging cable and / or power bank to ensure your mobile device always has power, especially during a long trip. You should also bring your blood glucose meter for calibration and as a backup.

For more information, please check travel content on training website.

When at the airport you can leave the sensor on your body to pass through full-body scanners. Keep your medical certificate ready for any queries from security personnel. Spare sensors inside your luggage can pass through airport screenings as well.

If airplane mode is enabled on your mobile device, Bluetooth® may automatically turn off. This can prevent mySugr Glucose Insights from communicating with your sensor. In this case, to re-establish the communication despite the active flight mode, you should turn Bluetooth® back on. For more information on how to do so, see the User’s Manual of your mobile device.

Please consider that both iOS and Android devices remember the Bluetooth® state when airplane mode was enabled for the last time, and they will revert to that state the next time airplane mode is turned on. You can usually confirm if airplane mode is active by checking your mobile device's status bar.

On most airplanes, the operation of devices with active Bluetooth® connectivity is now officially permitted. However, to be on the safe side, check in advance with the airline to see to what extent mobile device operation is permitted during the flight. During the flight, the mobile device must be switched to airplane mode.

Changing Time Zones:

If you travel to a different time zone, the time in your mobile device adjusts to the local time (as soon as you deactivate flight mode when you are travelling by airplane). The mySugr app also adopts the local time for all displayed CGM values, so there is no overlap or duplication of CGM values. This is possible because the values are stored in the background in a universal time (UTC) and are adjusted automatically to the time zone you are in.

If you want to go swimming you can keep the sensor on your body. The Accu-Chek SmartGuide sensor may be submerged for up to 60 minutes at a depth of up to 1 m (3.28 feet) . However, the adhesive can come off more easily in water, so using additional waterproof tape is recommended.

If you plan to spend time at high altitude, keep in mind that the Accu-Chek SmartGuide sensor is only guaranteed to work up to an altitude of 3000 meters (9,842 feet). Also clarify the allowable altitude for the blood glucose meter you are taking with you.

Keep in mind that physical activity has an effect on glucose levels, so it’s a good idea to regularly check your current level in the app when in doubt (e.g., when leaving your mobile device at the poolside when swimming).

The Accu-Chek SmartGuide sensor should be stored at temperatures between 2 °C and 27°C (35 and 81°F), i.e. either in a shaded place or in the refrigerator.
