1. A method, comprising:

  • receiving, using one or more processors, a plurality of time spaced analyte related data monitored by an analyte sensor in fluid contact with interstitial fluid during a first time period;

    detecting, using the one or more processors, when one or more of the received plurality of time spaced analyte related data crosses a predetermined analyte threshold level during the first time period;

    receiving, using the one or more processors, a plurality of time spaced temperature data during the first time period;

    determining, using the one or more processors, a rate of change of the received plurality of time spaced temperature data and detecting when the determined rate of change crosses a predetermined rate of temperature change;

    determining, using the one or more processors, a rate of change of the received plurality of time spaced analyte related data and comparing a slope of the determined rate of change of the received plurality of time spaced analyte related data to a slope of the rate of change of the received plurality of time spaced temperature data; and

    asserting, using the one or more processors, a notification when the determined rate of change of the received plurality of the time spaced temperature data reaches the predetermined rate of temperature change and when the one or more of the received plurality of time spaced analyte related data reaches the predetermined threshold analyte level during the first time period.
