What are the tests for blood glucose in endocrinology department

Endocrinology examination usually requires fasting blood glucose, 2-hour postprandial blood glucose, glycated hemoglobin, oral glucose tolerance test, insulin release test, and other tests. These tests help evaluate blood glucose levels, pancreatic function, and long-term blood glucose control. Fasting blood glucose is a measure of basal blood glucose levels, which requires not eating for at least 8 hours. Blood glucose levels 2 hours after meals reflect the ability to regulate blood glucose levels after eating, and blood should be collected 2 hours after the first bite. Glycated hemoglobin can reflect the average blood glucose level in the past 3 months and is not affected by short-term diet. The oral glucose tolerance test determines the degree of abnormal glucose metabolism by taking multiple blood samples after drinking glucose water. The insulin release test synchronously detects blood glucose and insulin levels to evaluate pancreatic beta cell function.

Three days before the examination, it is necessary to maintain a normal diet and activity level, and avoid deliberate dieting or vigorous exercise. Fast for 8 hours before fasting blood glucose test, but drink a small amount of water and avoid smoking, caffeine, and alcohol. The oral glucose tolerance test should be conducted on an empty stomach for 8-14 hours, and eating and vigorous activity should be avoided during the test. On the day of the examination, loose clothing should be worn to facilitate blood collection, and medical records and medication records should be carried. If you are taking medication that may affect blood sugar, please inform your doctor in advance. Some medications may need to be temporarily discontinued.
