Diabetes blood check needs to check the blood sugar level, glucose tolerance test, blood routine, glycosylated hemoglobin, blood ketone bodies, blood biochemical indexes, blood gas analysis and diabetes autoantibodies. 1. Blood sugar level. Including fasting blood glucose test, 2 hours postprandial blood glucose and random blood glucose test, fasting blood glucose needs to be carried out in the early morning fasting after 8~12 hours of fasting, the normal range of fasting blood glucose is 3.9~6.1mmol/L; random blood glucose can be carried out at any time of the day. 2. Glucose tolerance test (OGTT). It is mainly used to check the function of pancreatic islets, and requires eating a certain amount of glucose to detect changes in blood glucose levels before and after eating. 3. Blood routine. It belongs to the routine items of blood test and is mainly used to find out whether there is anemia, infection and other conditions. 4. Glycated hemoglobin. By testing the level of glycosylated hemoglobin in the blood, you can know the blood sugar level in 2~3 months. 5. Blood ketone bodies. By testing whether the level of ketone bodies in the blood is normal or not, we can determine whether there is diabetic ketosis or diabetic ketoacidosis. 6. Blood biochemical indicators. Can assess the body’s liver function, kidney function, as well as the presence of abnormal blood lipid levels. 7. Blood gas analysis. It can be used to determine the presence of ketoacidosis. 8. Diabetes autoantibody test. Mainly used to identify type 1 diabetes or type 2 diabetes. Consult the doctor promptly if there is any discomfort.
