Glycated hemoglobin 7.4% is elevated for both diabetics and normal people. Due to different testing methods and reagents, the reference index varies from hospital to hospital and needs to be analyzed specifically. Glycated hemoglobin reflects the average concentration of blood glucose over the past 2 to 3 months. Under normal circumstances, the reference range of glycosylated hemoglobin is 4%~6%, while glycosylated hemoglobin 7.4% is already significantly elevated, and it is recommended to consult a physician for treatment. For diabetic patients, the glycated hemoglobin should be controlled below 7%, so the glycated hemoglobin of 7.4% is also not up to the control target for diabetic patients. Patients with GHB 7.4% should undergo further tests and be diagnosed by a medical professional in order to avoid delays.
