Blood glucose standard ranges are important indicators for assessing an individual's carbohydrate metabolism status. Generally, standard blood glucose values are divided into two categories: fasting blood glucose and postprandial blood glucose.
1. Fasting blood glucose: This refers to blood glucose measured after at least 8 hours without eating, with a normal range of 3.9-6.1 mmol/L. This is the blood glucose value measured after at least 8 hours without caloric intake. For pregnant women, fasting blood glucose should not exceed 5.1 mmol/L. For patients with diabetes, it should be controlled between 4.4-7.0 mmol/L.
2. Postprandial blood glucose: Blood glucose levels 2 hours after a meal should be below 7.8 mmol/L. For pregnant women, the postprandial glucose standard is stricter; blood glucose 1 hour after a meal should be ≤10.0 mmol/L, and 2 hours after a meal ≤8.5 mmol/L. For diabetic patients, blood glucose 2 hours after a meal should not exceed 10.0 mmol/L.
However, these standards are not fixed and should be individually adjusted according to the patient's specific conditions, such as age, disease duration, and complications.
