1. What is the HbA1c test?


Diabetes is a chronic disease that is increasingly common in the community, including the young and the elderly.
The HbA1c blood test is one of the diabetes tests that helps to determine the amount of total glycosylated hemoglobin in the blood in percent.
More specifically, normal hemoglobin is always bound to glucose in the blood throughout the life of red blood cells, when glucose levels are elevated for long enough, glucose will react with hemoglobin without major catalysts. is glycosylation. Therefore, HbA1c level will be proportional to the patient's average glucose concentration in the previous 6-12 weeks, so from this index, it is possible to assess the patient's average blood glucose concentration in the previous 2-4 months. allows to evaluate the effectiveness of the diabetes treatment process as well as to support the screening and early diagnosis of diabetes.

2. Indicators in HbA1c . test results

Test result HbA1c% is the percentage of glycosylated hemoglobin in total hemoglobin with the following levels and diagnoses:
Normal: < 5.7% Pre-diabetes (increased risk of diabetes) diabetes): 5.7-6.4% Have diabetes: ≥ 6.5% When HbA1c rises above normal 1% equals your blood glucose value to increase 30mg/dl (1.7 mmol /L). In addition, if assessing the level of blood sugar control:
When HbA1c > 10%, the patient's blood sugar control is too poor. When HbA1c < 6.5%, blood sugar in the past time has been controlled. Patients need to control HbA1c < 6.5% because it can slow down and prevent eye, kidney and nerve complications caused by diabetes.

Conversely, the HbA1c result can be decreased in some cases such as: thalassemia, sickle cell disease, hemolytic anemia, splenectomy or pregnancy
In any case, the patient has both type 1 and type 1 diabetes. Type 2 should be tested for HbA1c at least twice a year, especially when blood sugar is unstable, so it should be tested more often at about every 3 months.
