Glycated hemoglobin 7.2% is elevated, may be diabetes, but only rely on glycated hemoglobin 7.2% can not confirm the diagnosis of diabetes mellitus, but also need to be combined with the patient’s clinical symptoms, as well as fasting blood glucose, 2 hours postprandial blood glucose or random blood glucose, etc. for comprehensive analysis. The diagnosis of diabetes mellitus is based on the typical symptoms of “three more and one less” (drinking more, urinating more, eating more, and weight loss) plus the measurement of intravenous plasma glucose ≥11.1mmol/L, fasting blood glucose ≥7.0mmol/L, or 2-hour blood glucose ≥11.1mmol/L after glucose tolerance test, which can be diagnosed if one of them meets the diagnosis. One of these is sufficient for a diagnosis of diabetes mellitus. It is recommended that patients with a glycated hemoglobin of 7.2% should go to the Department of Endocrinology of a regular hospital for detailed consultation and follow the doctor’s instructions.
