Fasting blood glucose normal value 1.General fasting whole blood glucose is 3.9-6.1 mmol/l (70-110 mg/dl), plasma glucose is 3.9-6.9 mmol/l (70-125 mg/dl). 2.Diabetes can be diagnosed when fasting whole blood glucose is ≥6.7 mmol/L (120 mg/dL) and plasma glucose is ≥7.8 mmol/L (140 mg/dL) with 2 repeated measurements. 3. When fasting whole blood glucose is above 5.6 mmol/L (100 mg/dL) and plasma glucose is above 6.4 mmol/L (115 mg/dL), glucose tolerance test should be done. Cheng Huayan, Department of Internal Medicine, Shengzhou Hospital of Traditional Chinese Medicine 4. When fasting whole blood glucose exceeds 11.1 mmol/L (200 mg/dL), it indicates that insulin secretion is extremely low or lacking. Therefore, when fasting blood glucose is significantly increased, diabetes can be diagnosed without other examinations. Normal value of postprandial blood glucose 1 hour after meal: blood glucose 6.7-9.4 mmol/L. At most, it should not exceed 11.1 mmol/L (200 mg/dl) 2 hours after meal: blood glucose ≤ 7.8 mmol/L. 3 hours after meal: return to normal after the third hour, each urine sugar is negative Normal blood sugar value for pregnant women 1, pregnant women fasting not more than 5.1 mmol/L 2, pregnant women 1 hour after meal: 1 hour after meal blood sugar value is generally used to detect pregnant women in diabetes detection, authoritative data shows that pregnant women 1 hour after meal shall not exceed 10.0 mmol/L to be the normal level of blood sugar; 3, pregnant women 2 hours after meal. The normal blood sugar value after meal is generally stipulated not to exceed 11.1mmol/L, while the normal blood sugar value 2 hours after meal for pregnant women is stipulated not to exceed 8.5mmol/L.
