Glycated hemoglobin 14.1% is abnormal for both normal people and diabetics, and it is much more serious than the normal value. The normal range of glycated hemoglobin is 3%~6%, 14.1% is an abnormal value, and it is recommended to further improve the fasting blood glucose, postprandial blood glucose and other tests to clarify the diagnosis. Glycated hemoglobin is clinically used to reflect the average level of blood glucose of the detector in the last 3 months, and has the role of assisting in guiding the treatment process and monitoring the condition of diabetic patients. Diabetic patients are required to have a glycohemoglobin control range of less than 7%, which can be relaxed in complicated cases such as poor underlying conditions, many complications, and short life expectancy etc. Whether a value of 14.1% is serious or not should be assessed in the context of the actual condition of the person being tested. In case of a glycosylated hemoglobin of 14.1%, it is recommended to go to the hospital and ask the doctor to make a judgment, rather than making a blind judgment on one’s own.
