Abstract

In some aspects, methods, devices, and systems for monitoring sensor data and indicating recommendations for confirmation tests on a user interface are provided. Sensor data is received and is monitored to detect predetermined signal characteristics that are associated with a likelihood of inaccuracy of the sensor data. A recommendation for a confirmation test to be performed is indicated on a user interface after the occurrence of a predetermined signal characteristic is detected.

Claims

1. A method of monitoring sensor data and indicating recommendations for confirmation tests on a user interface, the method comprising:

receiving sensor data over time, wherein the sensor data is derived from an in vivo positioned analyte sensor;

detecting, with processing circuitry, an occurrence of a predetermined signal characteristic in the sensor data, wherein the predetermined signal characteristic is associated with a likelihood of inaccuracy of the sensor data; and

indicating, on a user interface, a recommendation for a confirmation test after the occurrence of the predetermined signal characteristic is detected.

2. The method of claim 1, wherein the one or more predetermined signal characteristic comprises a time period associated with a time of sensor insertion.

3. The method of claim 1, wherein the one or more predetermined signal characteristics comprises high rates of change in the sensor data.

4. The method of claim 1, wherein the one or more predetermined signal characteristics comprises a predetermined magnitude range for the sensor data.

5. The method of claim 4, wherein the predetermined magnitude range is associated with low levels of analyte.

6. The method of claim 1, wherein the one or more predetermined signal characteristics comprises exceeding a minimum threshold level of calculated accuracy or confidence in accuracy.

7. The method of claim 1, wherein the one or more predetermined signal characteristics comprises a signal irregularity.

8. The method of claim 7, wherein the signal irregularity comprises an occurrence of a spike in the sensor data generated by one or more signal outliers in the sensor data, wherein the spike has an associated rate-of-change of 5 mg/dL per minute or greater.

9. The method of claim 7, wherein the spike is an occurrence of a spike in the sensor data generated by one or more dropouts in the sensor data, wherein the spike has an associated rate-of-change of 5 mg/dL per minute or greater.

10. The method of claim 7, comprising calculating slopes for the sensor data, wherein the signal irregularity is determined based on the calculated slopes.

11. The method of claim 1, comprising temporarily disabling one or more features of the analyte monitoring system after the occurrence of the predetermined signal characteristic is detected.

12. The method of claim 11, wherein the one or more features include a therapeutic recommendation based on the sensor data.

13. The method of claim 11, comprising:

receiving an indication of user input acknowledging the recommendation for a confirmation test; and

re-enabling the one or more features of the analyte monitoring system.

14. The method of claim 11, wherein the indication of the user input includes an indication of a completion of a confirmation test.

15. The method of claim 1, wherein the recommendation for the confirmation test is displayed on a display of the user interface.

16. The method of claim 1, wherein the sensor data is derived from interstitial fluid and the recommendation for a confirmation test is a recommendation for a blood-derived confirmation test.

17. The method of claim 1, wherein the analyte is glucose or a ketone body or both.

18. The method of claim 1, comprising removing the indication of the recommendation for the confirmation test after a predetermined condition occurs.

19. The method of claim 18, comprising:

detecting, with the processing circuitry, an occurrence of a subsequent predetermined signal characteristic in subsequent sensor data received; and

indicating, with the user interface, a subsequent recommendation for a confirmation test after the subsequent occurrence of the subsequent predetermined signal characteristic is detected.

20. The method of claim 18, wherein the predetermined condition is a completion of a confirmation test.

21. The method of claim 18, wherein the predetermined condition is a completion of a confirmation test resulting in a confirmation of accuracy.

22. The method of claim 18, wherein the predetermined condition is an absence of any predetermined signal characteristics in the sensor data.

23. The method of claim 18, wherein the predetermined condition is an elapse of a predetermined period of time.

24. The method of claim 23, wherein the predetermined period of time is between 1 and 3 hours after the detection of the predetermined signal characteristic.
