Description
HbA1c measures average blood glucose over 2–3 months to diagnose or monitor diabetes; patients in China may need it for routine checkups or treatment adjustment, with lab costs typically ¥15–¥45, and ChinaMedicalHub can assist with hospital booking and interpreter support.
Main Uses
HbA1c is primarily used to diagnose diabetes, monitor long-term glucose control in people with diabetes, and assess the risk of developing diabetes-related complications. It is also useful in adjusting treatment plans and evaluating the effectiveness of diabetes management over time.
Normal Range
The normal range for HbA1c (glycated hemoglobin) is typically between 4% and 5.6%. A value of 5.7% to 6.4% indicates prediabetes, while 6.5% or higher on two separate tests is diagnostic for diabetes.
Low Values - Possible Causes
Possible causes of low HbA1c values include: recent blood loss or transfusion, hemolytic anemia, iron deficiency anemia, pregnancy, and short-term fluctuations in glucose levels due to diet or medication changes.
High Values - Possible Causes
Possible causes of high HbA1c values include: uncontrolled diabetes, chronic kidney disease, liver disease, obesity, and certain medications that can increase blood sugar levels such as corticosteroids or antipsychotics.
