Glucose tolerance tests can be done on an outpatient basis.
Glucose tolerance test is a test method to diagnose diabetes, which can determine the function of pancreatic β-cells and their ability to regulate blood glucose through the test results. The specific test method is as follows: first, venous blood is drawn once on an empty stomach, then 75 grams of anhydrous glucose is dissolved in 300 milliliters of water and drunk, and blood glucose levels and insulin levels are measured half an hour, one hour, two hours, and three hours after drinking the glucose water.
You are not allowed to eat or drink between each blood draw during the glucose tolerance test, otherwise the accuracy of the results will be affected. When measuring fasting blood glucose, it is required to fast for 8-10 hours the night before; the daily carbohydrates should not be less than 150g for three days before the test; some drugs that affect the results such as birth control pills and diuretics should be stopped before the test, and they need to be stopped for 3-7 days if the condition permits.
Drinking sugar water during the glucose tolerance test requires that you drink it within 5 minutes, do not smoke or drink alcohol after drinking sugar water, do not drink coffee or tea, and do not do strenuous exercise in order to ensure the accuracy of the glucose tolerance test.
It is recommended that patients who need to undergo glucose tolerance test should go to regular hospitals in time, and standardize the diagnosis and treatment under the guidance of doctors, so as to avoid delaying the condition.
