Abstract

A method includes: measuring a blood glucose (bG) level in a blood sample; storing the bG level and a time of receipt of the blood sample; storing a classification of the blood sample; in response to the receipt of the blood sample, selecting a group of stored bG levels having the classification of the blood sample and that were received within a predetermined period before receipt of the blood sample; calculating a bG evaluation parameter from the selected bG levels; evaluating the bG evaluation parameter in relation to first predetermined criteria, the first predetermined criteria including a first threshold indicative of a high bG level or a low bG level; selectively displaying an indication of recognition of a pattern in the selected bG levels when the bG evaluation parameter is greater than or less than the first threshold; and selectively removing the indication from the display.
