Abstract

Methods and devices for providing calibration in analyte monitoring systems are provided.

Claims

1. An analyte monitoring device, comprising:

an operative component adapted to measure an analyte concentration from a sample obtained from a testing location of a user; and

a receiver adapted to receive a signal from the operative component relative to the measured analyte concentration, wherein the receiver is configured to store information corresponding to the analyte concentration and the testing location to process analyte related signals based at least in part on the stored analyte concentration information and the testing location information.

2. The analyte monitoring device of claim 1, wherein the receiver includes a user interface for providing the testing location information.

3. The analyte monitoring device of claim 2, wherein the user interface includes one or more of a keyboard, or a touch screen monitor to select the testing location from a database of testing locations.

4. The analyte monitoring device of claim 3, wherein the touch screen monitor displays a physiological model to select the testing location from the physiological model, wherein the testing locations retrieved from the database is associated with the corresponding location displayed on the physiological model.

5. The analyte monitoring device of claim 4, wherein one or more regions of the physiological model are highlighted in response to manipulation of the user interface.

6. The analyte monitoring device of claim 1, wherein the analyte is glucose.

7. The analyte monitoring device of claim 1, wherein the operative component is an analyte test strip.

8. The analyte monitoring device of claim 1, wherein the stored analyte level is used to calibrate the analyte monitoring device.

9. The analyte monitoring device of claim 8, wherein the testing location and corresponding analyte level concentration is used determine or correct blood-to-interstitial glucose lag.

10. The analyte monitoring device of claim 1, wherein the receiver is a component of a continuous glucose monitoring system.

11. The analyte monitoring device of claim 10, wherein the receiver is configured to receive a signal from a transmitter in signal communication with an analyte sensor, where the received signal is indicative of an analyte level.

12. The analyte monitoring device of claim 1, wherein the receiver is a component of an on-demand glucose monitoring system.

13. The analyte monitoring device of claim 1, wherein the testing location is selected from the group comprising a hand, finger, palm, arm, abdomen, thigh, and a calf.

14. The analyte monitoring device of claim 1, wherein the receiver is configured to output the testing location.

15. The analyte monitoring device of claim 14, wherein the receiver includes a display to indicate the testing location.

16. The analyte monitoring device of claim 15, wherein the display includes a physiological model that indicates the testing location.

17. The analyte monitoring device of claim 15, wherein the display includes a textual message to indicate the testing location.

18. A method for calibrating an analyte sensor, comprising:

retrieving a first calibration measurement;

requesting a current calibration measurement;

receiving the current calibration measurement;

comparing the first calibration measurement to the current calibration measurement; and

calibrating the analyte sensor based on one or more of the retrieved first calibration measurement or the received current calibration measurement if the current calibration measurement is outside a threshold value compared to the first calibration measurement.

19. The method of claim 18, wherein the threshold includes one of at least about 50 mg/dL, at least 100 mg/dL, or greater than about 150 mg/dL.

22. The method of claim 18, wherein the current calibration measurement includes a blood glucose measurement measured by a blood glucose monitor in response to the request for a current calibration measurement.

23. The method of claim 18, further comprising updating a calibration schedule if the current calibration measurement is outside a threshold value compared to the first calibration measurement.

24. The method of claim 23, wherein the calibration schedule is only updated if the current calibration measurement is within a predetermined time period from a next scheduled calibration measurement.

25. The method of claim 24, wherein the predetermined time period includes 2 hours or less.

26. The method of claim 18, further comprising notifying a user if the current calibration measurement is not outside a threshold value compared to the first calibration measurement.

27. The method of claim 18, further comprising requesting a new calibration measurement if the current calibration measurement is outside a threshold value compared to the first calibration measurement.

28. The method of claim 27, further comprising waiting a predetermined time period prior to requesting a new calibration measurement.
