Disease description:

After undergoing a medical examination at the hospital as part of the employment requirement, my blood test report showed elevated glycated hemoglobin levels. However, I don't know how to interpret this result. So I would like to ask, what does it mean when glycated hemoglobin is high?

Glycated hemoglobin (HbA1c) is a blood test that measures the average blood glucose level over the past three months. A high HbA1c level indicates elevated blood glucose and may be a sign of diabetes. Diabetes is a chronic condition characterized by persistently high blood glucose levels, which can lead to serious complications such as heart disease, kidney disease, retinopathy, and neuropathy.
