What is the normal range for blood glucose?
Blood glucose concentrations change throughout the day. They are typically higher after eating and lower during fasting. A fasting blood glucose level lower than 6mmol/l is normal. A fasting blood glucose of 7mmol/l or higher may indicate diabetes. Diabetes is a long-term condition where the body is not able to control the amount of glucose in the blood. If your fasting blood glucose level is below 7mmol/l but above 6mmol/l you may have IFG or impaired glucose tolerance (IGT). IFG and IGT are not diabetes but suggest that your body is not converting glucose to energy as efficiently as it should. For the range of blood glucose concentrations associated with IFG, see Diagnosis.
