Glucose 6.19 generally refers to a blood sugar of 6.19 mmol/L. If the fasting blood sugar is 6.19 mmol/L, it is slightly higher than normal, and if the two-hour postprandial blood sugar is 6.19 mmol/L, it is within the normal range. Fasting blood glucose refers to the blood glucose value detected in the plasma taken before breakfast after overnight fasting (at least 8 to 10 hours without any food, except drinking water), the normal range of fasting blood glucose is 3.9~6.1mmol/L, so if the fasting blood glucose is 6.19mmol/L, it is slightly higher than the normal fasting blood glucose range. The normal range of two-hour postprandial blood glucose should be less than 7.8mmol/L, so if the two-hour postprandial blood glucose is 6.19mmol/L, then it is within the normal range. It is recommended that you seek medical attention if you have an abnormal blood glucose level.
