Abstract

Described are methods and systems for determining clusters of glucose data that can be utilized to provide insights to the person with diabetes, such as, for example, when a certain number of measurements during a predetermined time period is less than a predetermined threshold so that the subject is notified that the number of glucose measurements is less than optimum for management of diabetes.

Claims

1. -5. (canceled)

6. A system for management of diabetes of a subject, the system comprising:

at least one glucose monitor that is configured to measure a glucose concentration based on an enzymatic reaction with physiological fluid in a biosensor that provides an electrical signal representative of the glucose concentration; and

a controller in communication with at least one glucose monitor, the controller being configured to receive or transmit glucose data representative of glucose levels measured by the glucose monitor over a predetermined time period to determine plural clusters of glucose data with respect to glucose levels so that the glucose levels with reference to a predetermined time period are correlated to each other in a cluster due to their similarity as compared to glucose levels in other clusters and at least three clusters of glucose levels are provided to indicate the distribution of the glucose levels;

wherein the controller annunciates an indication of the distribution of the at least three clusters into respective first range, second range, and third range of glucose values.

7. The system of claim 6, in which the first range of glucose values comprises a minimum greater than a maximum of the second range, which has a minimum greater than a maximum of the first range.

8. The system of claim 7, in which the minimum of the first range comprises about 180 mg/dL of glucose, the minimum of the second range comprises about 70 mg/dL.

9. The system of claim 7, in which each of the clusters comprises glucose measurements with respect specific time intervals within the predetermined time period so that a message of a distribution of at least one cluster within one of the first, second and third ranges is annunciated.
