Blood glucose fasting 4.6mmol / L, two hours after the meal 7.6mmol / L are generally within the normal range. Normal fasting blood glucose range is 3.9~6.1mmol/L, two hours after meal blood glucose normal range should be less than 7.8mmol/L, so blood glucose fasting 4.6mmol/L, two hours after meal 7.6mmol/L are within the normal range. When fasting blood glucose is greater than or equal to 6.1mmol/L but less than 7.0mmol/L and 2 hours after sugar load blood glucose is less than 7.8mmol/L, it suggests impaired fasting blood glucose. When fasting blood glucose is less than 7.0 mmol/L but 2-hour post glycemic load blood glucose is greater than or equal to 7.8 mmol/L and less than 11.1 mmol/L, it suggests impaired glucose tolerance. It is recommended to visit a hospital when abnormal blood glucose values occur.
