Glucose Predict

The app predicts where your glucose levels might go in the next 2 hours. This prediction is based on your past CGM values, and your carbohydrate and insulin entries in the Accu-Chek SmartGuide app logbook.

The glucose prediction displays on the graph on the Home screen when at least 1 hour of uninterrupted CGM data is transferred successfully to the app.

The graph shows your glucose levels during the previous hour, as they are now, and their predicted range for the next 2 hours. The dotted line in the predicted range represents your projected average glucose value.
The accuracy of your predicted glucose range decreases the further out in time it is, as shown by the expanding vertical bars.

Remember that the displayed future glucose values are predictions that may vary from the actual values and are unaffected by the current status of the Trend Mode or the Therapy Mode in the Accu-Chek SmartGuide app. The Trend Mode indicates that the displayed values in the Accu-Chek SmartGuide app should only be used to see trends and as a general reference. Only the values displayed in Therapy Mode can be used for making therapy decisions.

The range shown in the graph is from 0 to 300 mg/dL (0–16.7 mmol/L). If your value is above 300 mg/dL (16.7 mmol/L), it will be identified by a triangle pointing upward, and the app displays HI instead of a numerical value if your value is above 400 mg/dL (22 mmol/L). If your value is low, below 40 mg/dL (2.2 mmol/L), it will be identified by a triangle pointing downwards, and the app displays LO instead of a numerical value.

If your predicted glucose is trending towards a low, and if a Low Glucose Predict card appears, only the glucose values up to the next 30 minutes display in the graph. If your predicted glucose does not reach a low within the 30 minutes, then no prediction values are displayed in the graph and only the Low Glucose Predict card appears.

Keep in mind the following when viewing your prediction:

  • The Predict app makes predictions based on your CGM data and logged carbs and insulin. Any actions you might take in the next two hours (such as eating, taking insulin, and exercising) are not factored in to the prediction.
  • The 2-hour prediction is informational only in cases where the prediction is for more than 45 minutes, and to make you aware of future actions you may need to take (such as checking your glucose more frequently, preparing insulin injections, or having carbs readily available). In the cases of high and low glucose predictions within the next 45 minutes, you should consider what actions you will need to take.
