If your reading was taken before the meal, 4.4 mmol/L is equivalent to 79 mg/dL and is within target range . After a meal, 79 would be on the low side of normal. For most people with diabetes, the blood glucose target before eating is 70 to 130 mg/dL (3.9-7.2 mmol/L). Two hours after eating, the blood glucose target is less than 180 mg/dL (10.0 mmol/L). At bedtime the target is 90 to 150 (5.0-8.3 mmol/L). Less than 70 mg/dL (3.9 mmol/L) is considered low. It is best to try to think of numbers in terms of high and low, not good or bad. All numbers are good in the sense that they give you information that will better help you understand your diabetes.
