For diabetic patients, the three most basic checkups are blood glucose, glycosylated hemoglobin and urine routine.1. Blood glucose includes fasting and two-hour postprandial blood glucose, fasting blood glucose less than 7mmol/L and two-hour postprandial blood glucose less than 10mmol/L is up to standard.2. Glycosylated hemoglobin, a non-enzymatic glycosylation product of glucose and hemoglobin, represents the past 2-3 months’ blood glucose control level, the normal value is 4%-6%. Glycosylated hemoglobin makes up for the defect that blood glucose only represents instantaneous blood glucose, but it is easily affected by hemoglobin, and abnormal hemoglobin quality and quantity may affect the result of glycosylated hemoglobin. 3. urine routine, urine protein in urine routine examination can detect early diabetic nephropathy, urine ketone body is used to diagnose diabetic ketosis, urine sugar is a simple indicator of blood glucose control, urine occult blood, urine leukocytes are used to determine There is no urinary tract infection, simple diabetes examination three items are these three.
