Description
The Hemoglobin A1c test measures average blood sugar over 2–3 months to diagnose or monitor diabetes; patients in China can arrange hospital testing with interpreter and booking support through ChinaMedicalHub for ¥200–¥500.
Main Uses
HbA1c testing 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, sickle cell anemia, thalassemia, and conditions that shorten the lifespan of red blood cells.
High Values - Possible Causes
Possible causes of high HbA1c values include: uncontrolled diabetes, chronic kidney disease, liver disease, iron deficiency anemia, and certain medications such as corticosteroids.
