Methods, devices and system for providing diabetic condition diagnosis and therapy

A method of determining fasting glucose level information, comprising:

• performing a meal start time determination for each one day time period, wherein performing the meal start time determination includes:
• retrieving from a storage unit a meal start time of day period;
• retrieving an insulin delivery information within the meal start time of day period;
• identifying an insulin delivery time within the meal start time of day period;
• retrieving glucose data collected during the meal start time of day period;
• determining a potential meal start time within the meal start time of day period by identifying an upward trend in the glucose data;
• comparing the insulin delivery time with the potential meal start time;
• and
• setting the meal start time as the determined potential meal start time when the insulin delivery time correlates with the potential meal start time based on the comparison;
• determining a plurality of fasting metrics, each fasting metric corresponding to a respective one day time period, wherein determining each fasting metrics includes:
• retrieving a plurality of glucose data collected over a fasting period, the fasting period preceding the determined meal start time;
• and
• determining a median, mean, minimum, or maximum of the retrieved plurality of glucose data over the fasting period;
• determining an overall fasting metric, wherein the overall fasting metric is determined by applying a function to the determined fasting metric, the function including one or more of a median, a mean, a standard deviation, an interquartile range, a minimum, or a maximum;
• generating fasting glucose level information using the overall fasting metric;
• generating diagnosis information using the fasting glucose level information, wherein the generated diagnosis information provides an indication of a diabetic condition or a pre-diabetes condition;
• and
• outputting the diagnosis information on a user interface.
