First Claim
1. A method of determining analyte trends, comprising:
- receiving in vivo derived analyte measurements;
calculating, with a processor, initial trends as level or non-level based on a rate-of-change for a current analyte measurement and at least one past analyte measurement, wherein an initial trend is level when the rate-of-change is zero or within a predetermined tolerance range for zero; and
determining, with the processor, whether final trends for display on a user interface are level or non-level, wherein the final trend determinations are based on the initial trend calculations and whether a change-resistant state is active;
wherein when the change-resistant state is active, a minimum threshold of change is required between the current analyte measurement and a past analyte measurement selected as a reference in order for a final trend to transition from level to non-level;
wherein a change-resistant state is activated each time a final trend is determined to be level and deactivated each time a final trend is determined to be non-level; and
wherein the minimum threshold of change varies depending on the value of the current analyte measurement.

Abstract
Methods, devices, and systems are provided that determine analyte trends according to different methods depending on whether a change-resistant state is active or not active. The method used when the change-resistant state is activated provides for different requirements for a resulting analyte trend to transition between states (e.g., level to non-level). Furthermore, in some aspects, methods, devices, and systems of selecting or modifying a response rate of an analyte monitoring device for an individual user are provided. User instructions for selecting or modifying a response rate of the device or system is received externally via a user interface or communication channel. The response rate of the analyte monitoring device or system is then selected or modified to the first response rate, and the device or system operated with the first response rate.
