What is the normal reference range for the 75g glucose screening test?
75g glucose screening generally refers to the glucose tolerance test. Under normal circumstances, the reference range for normal values is a fasting blood glucose level of 3.9–6.1 mmol/L and a 2-hour post-glucose load blood glucose level of 4.4–7.8 mmol/L. The specific analysis is as follows:
The glucose tolerance test is a method used to diagnose diabetes by measuring blood glucose levels before and 2 hours after ingesting 75g of oral glucose. The oral glucose tolerance test (OGTT) is an important diagnostic tool for diabetes. It is recommended that individuals with blood glucose levels above the normal range undergo a 75g oral glucose tolerance test, regardless of whether their levels meet the diagnostic criteria for diabetes. The procedure involves collecting a fasting blood sample, dissolving 75g of glucose in approximately 250ml of warm water, and drinking it within 5 minutes. Blood glucose levels are then measured again 2 hours after ingestion. During the glucose tolerance test, the normal reference range for fasting blood glucose is 3.9–6.1 mmol/L, while the normal reference range for blood glucose 2 hours after glucose intake is 4.4–7.8 mmol/L. If a patient's fasting blood glucose exceeds 6.1 mmol/L or the 2-hour post-glucose blood glucose exceeds 7.8 mmol/L, diabetes may be preliminarily diagnosed. Patients can, under medical guidance, use medications such as metformin hydrochloride tablets, gliclazide modified-release tablets, and glimepiride capsules for treatment.
It is recommended that patients maintain a light diet in daily life, consume appropriate amounts of vitamin-rich fruits and vegetables, and avoid high-sugar foods to prevent adverse effects on health.
