Abstract

Embodiments of the invention provide apparatus, systems and methods wherein pre-event and post-event analyte concentration readings associated with an event are collected and processed to determine a numerical delta. The numerical delta may be displayed on a visual display to aid in a ready determination of the affect that the event (alone or in combination with medication and/or insulin dosages) had on the analyte concentration levels. Medication and/or insulin dosages may be displayed alongside the numerical delta to gauge immediate relationships between numerical delta, dosage and/or an associated event. Apparatus and systems for calculating and displaying the numerical delta are described, as are other aspects.

Claims

1. A method of determining and displaying blood analyte values, comprising:

measuring a pre-event analyte concentration reading and a post-event analyte concentration reading, both associated with a first event, with an analyte measurement device; and

calculating a numerical delta between the pre-event analyte concentration reading and the post-event analyte concentration reading for the first event.

2. The method of claim 1 further comprising displaying on a visual display, the numerical delta associated with the first event.

3. The method of claim 2 further comprising displaying on the visual display, an insulin dose associated with the first event along with the numerical delta.

4. The method of claim 2 further comprising:

determining if the numerical delta is within a predetermined acceptable range; and

indicating that the numerical delta is within the predetermined acceptable range with a first indicator.

5. The method of claim 4 wherein the first indicator is selected from a group consisting of:

a first displayed color, and

a first displayed graphic.

6. The method of claim 2 further comprising:

determining if the numerical delta is outside of a predetermined acceptable range; and

indicating that the numerical delta is outside of the predetermined acceptable range with a second indicator.

7. The method of claim 2 wherein the second indicator is one selected from the group consisting of:

a second displayed color, or

a second displayed graphic.

8. The method of claim 2 wherein the first event is a meal event and the pre-event analyte concentration reading is a preprandial analyte concentration reading and the post-event analyte concentration reading is a postprandial analyte concentration reading.

9. The method of claim 2 wherein the first event is an exercise regimen.

10. The method of claim 2 wherein the numerical delta is displayed along with numerical deltas for a plurality of additional events.

11. The method of claim 2 wherein the numerical delta is displayed on an analyte meter.

12. The method of claim 1 wherein a graphical display of an analyte concentration level on a first axis is displayed against time on a second axis, and the numerical delta is displayed adjacent to a peak in the graphical display of the analyte concentration level.

13. The method of claim 12 wherein an insulin dosage is also displayed adjacent to the peak in the graphical display of the analyte concentration level.

14. The method of claim 1 wherein the numerical delta is normalized as against another measure associated with the first event.

15. An apparatus operative to calculate and display analyte concentration information, comprising:

a measurement subsystem adapted to measure a pre-event analyte concentration reading and a post-event analyte concentration reading, both associated with a first event; and

a processor coupled to the measurement subsystem and operative to receive the pre-event and post-event analyte concentration readings and calculate a numerical delta between the pre-event analyte concentration reading and the post-event analyte concentration reading associated with the first event.

16. The system of claim 15 further comprising a visual display operative to display the numerical delta associated with the first event.

17. The system of claim 15 wherein the numerical delta is normalized as against another measure associated with the first event.

18. A system operative to determine and display analyte concentration information, comprising:

a measurement apparatus operative to measure a pre-event analyte concentration reading and a post-event analyte concentration reading, both associated with a first event;

a host device adapted to communicate with the analyte measurement system and adapted to receive the pre-event and post-event analyte concentration readings associated with the first event, the host device including;

a processor operative to calculate a numerical delta between the pre-event and post-event analyte concentration readings for the first event.

19. The system of claim 18 further comprising a visual display operative to display the numerical delta associated with the first event.

20. The system of claim 19 wherein the visual display is operative to display an insulin dosage associated with the first event along with the numerical delta.
