Night Low Predict

The Night Low Predict feature lets you know, before going to bed, your chance of having low glucose during the night, and also provides the time period during which the risk of a low will most likely occur. The prediction is available between 9 pm and 2 am.

Going low means that your glucose value might go below 70 mg/dL (3.9 mmol/L). The Night Low Predict feature functions with a fixed low threshold of 70 mg/dL (3.9 mmol/L) that is independent of the Accu-Chek SmartGuide app.

A night is defined as a 7-hour time period that counts from the time the prediction is calculated.

You can set up the Night Low Predict feature and manually request a new calculation, for any period of time between 9 pm and 2 am. You can also be notified at selected times of high risk (significantly above your normal risk).

If there's a high chance of having low glucose during the night, and notifications are on, the Night low predicted! notification will show up on your mobile device's Lock screen. The Night Low Predict card can be seen below the graph on this app's Home screen. Go to Menu > Notification settings to manage this notification.

Tap the notification or card to see the graphic prediction on the Night Low Predict screen.

The probability of having low glucose during the night is divided into 3 different risk levels, with a different color representing each level:

  • Normal — less than 30% (green)
  • High — between 30–60% (yellow)
  • Very high — above 60% (red)

Whether your chance of having low glucose during the night is normal, high, or very high, consider what actions you will take.

Even a normal risk is still a risk, so any necessary actions should still be considered.

The Night Low Predict screen also displays the following recommendations when there is a high or a very high chance of having low glucose during the night.

  • Keep carb snacks within reach by your bed.
  • Consider injecting fewer units of basal insulin at night.
  • Have some food rich in proteins or fat.

You can manually request a calculation of your chance of having low glucose every 20 minutes, as long as it is 20 minutes after your last meal and/or insulin injection, with the following exceptions:

  • Your glucose value is already below 70 mg/dL (3.9 mmol/L) or below your Low Glucose Limit (if above 70 mg/dL (3.9 mmol/L)).
  • Your glucose prediction or the Low Glucose Predict card has indicated you are about to go below 70 mg/dL (3.9 mmol/L). Your glucose value may differ from the glucose value shown here, as this value is based on the Low Glucose Limit you set for your glucose alarms in the Accu-Chek SmartGuide app.
