A glycated hemoglobin test is a very important and accurate blood test for suspected or tested diabetes mellitus. It has a lot of advantages compared to the standard two-hour glucose test and as a result it costs more. However, its advantages: a more accurate result, ease of implementation, speed and reliability, can endure such a disadvantage as cost.
In this article you will find answers to many basic questions regarding one of the blood sugar tests. We will look at what a blood test for glycated hemoglobin is, how it differs from other blood sugar tests, what

What does glycosylated hemoglobin show?
Glycolized hemoglobin is often referred to as glycated. In fact, the result of the analysis shows in percentage what part of hemoglobin is associated with glucose.
Hemoglobin is a protein in the blood, whose role is to saturate all the cells of the body with oxygen. If glycated hemoglobin is elevated, this task is poorly performed and there is a high risk of diabetes.
As the result of the analysis is provided as a percentage, the norm for adults and children is the same. This analysis can not be fooled by the weekly diet, which is very common among adolescents. All eaten in three months is reflected in the normal glycated hemoglobin in the blood.
In the analysis, this result is most often designated as HbA1C, but such a recording form as “hemoglobin A1C” is also acceptable, “glycosylated hemoglobin hba1c” can also be found in the analysis. Sometimes the word hemoglobin is completely omitted.
There are special tables by which you can compare the percentage result of the analysis with the glucose content. So, if the analysis shows 4%, this means that 3.8 mmol / l of glucose has been on average in blood over the past three months. Value HbA1C and glucose in mmol / l give below:
|HbA1C,%||mmol / l of glucose 3.8|
|6||5.4 7.0 8.6|
|9||10.2 11.8 13.4|
The rate of glycated hemoglobin
Having figured out how much glucose corresponds to the hemoglobin associated with it, consider what value it should take in a healthy person or a stable diabetic.
- If the percentage of hemoglobin associated with glucose is less than 5.7, this means that you have a stable healthy state, the exchange of carbohydrates is carried out correctly, the risk of diabetes is not observed.
- If glycated hemoglobin is increased slightly: 5.7 - 6.0%, it is worth switching to a low carbohydrate diet. This is necessary to prevent diabetes. And although the risk of getting it is still small, it is worth caution.
- With a result of a 6.0-6.4% transition, a diet low in carbohydrates and a healthy lifestyle is extremely necessary. Delay no longer. The risk of diabetes is very high.
- If, after determining the glycated hemoglobin, its percentage is more than 6.5, the doctor may preliminarily make a diagnosis of diabetes. To clarify it, of course, still need additional procedures.
- The rate of glycated hemoglobin for diabetics can be considered different in a different source. Generally, they say that when the content of HbA1C does not exceed 7%, diabetes is compensated and the condition is stable. But some doctors, for example, such as Dr. Bernstein, insist that diabetics should strive for a rate from 4.2 to 4.6%.The same interval is typical for slender healthy people, diabetics should reach for it. However, in the pursuit of compensating for diabetes, one may not notice the risk of hypoglycemia. In order to avoid this, it is necessary to optimize your diet and learn to maintain a balance between sugar and hypoglycemia.
How to get tested for glycated hemoglobin?
. As it is much easier and faster to pass the analysis of glycated hemoglobin than for glucose tolerance, many patients prefer to save time and effort. Find time for such a blood test at any time of the day. Advantages of glycosylation:
- The test does not necessarily take on an empty stomach in the morning. It is not sensitive to just taken food. It can be taken even after exercise, for example, training in the gym, after a working day or at any other convenient time of the day.
- It does not respond to temporary abnormalities such as, for example, a cold, emotional stress or seasonal infection. The intake of drugs against these diseases is also not captured by the analysis. Only diabetes medications affect the results of
- . Blood donation for sugar that is taken on an empty stomach is less accurate than glycated hemoglobin.
- The percentage of certain hemoglobin suggests that the rate of glycated hemoglobin in women is the same as in men.
- Gives a detailed picture of the diet( or lack thereof) in a patient over the past three months.
- For rent quickly, easily for both the patient and the doctor.
Disadvantages of the
analysis Although the analysis has a number of specific advantages, it is certainly not perfect.
- Compared to conventional glucose testing, the review costs more.
- Not suitable for people suffering from anemia and hemoglobinopathy.
- Distributed only in good clinics, resulting in reduced availability in remote areas.
- An unsuccessful choice for expectant mothers who are in the position: glycated hemoglobin in pregnant women reflects elevated sugar only after 3 months, and during this period one could take measures to eliminate deviations from the norm. In addition, the mother's sugar level in blood begins to grow only from the sixth month, so that the glycated hemoglobin will reflect this only by the date of birth.
- The reasons why glycated hemoglobin is elevated can be affected by an increased amount of thyroid hormones.
Healthy people should be tested for HbA1C at least once every three years; in diabetics, this period is reduced to three months.
