A new parameter of metabolic control derived from the results of continuous blood glucose monitoring is time in range (TIR). According to current recommendations, in pregnant women with diabetes, this glycemic range is defined by values of 3.5 to 7.8 mmol/L, with the aim of keeping glycemia in this range as much time as possible, and at the same time reducing the time spent below its lower limit (< 3.5 mmol/L). In pre-gestational type 1 diabetes, it is recommended to reach this TIR above 70% of the total measurement time including up to 4% of simultaneous time spent in hypoglycemia. In gestational (and pre-gestational type 2) diabetes, the recommended % of in-range times are not yet specified.
