HbA1c normal range

The red blood cells in the body contain protein molecules called hemoglobin. One of the primarily job responsibilities of hemoglobin is to carry the oxygen that is produced by the body to the various organs and tissues of the body and in return carry back the carbon dioxide to the lungs.

We all know that when sugar sticks to a particular surface, its removal can become cumbersome. The same logic is applicable even to the body. Individuals with high levels of sugar in the body often have glycated hemoglobin in the blood.

The high levels of sugar in the body cause the sugar to attach itself to the hemoglobin resulting in the formation of a layer of sugar on it. Red blood cells generally tend to live for about one hundred and twenty days in the bloodstream. This in turn enables the hemoglobin A1c range test to find out the blood sugar levels present in the body for almost the last three months.

A hemoglobin A1c range test is better and more reliable than the normal glucose monitoring that is done at home.

Hemoglobin A1c normal range

  • Most of the hemoglobin A1c tests that are conducted to determine the normal range vary from one laboratory to another.
  • According to medical experts, the normal hbA1c range is usually between 4 to 6 percent. There is some medical opinion which suggests that diabetic individuals should have hbA1c levels below 7 percent.
  • A test result that shows hbA1c levels greater than seven percent is a definite indicator of poor control and maintenance of blood sugar and diabetes over the past few months. In such cases, future instances of micro-vascular complications and risks can be significantly reduced by getting the hbA1c levels within the mandatory normal range.
  • Since, an hbA1c test is used to determine the blood sugar level; it is a very helpful tool to prevent the development of possible medical complications of the body that arise from the presence of diabetes. A higher than normal hbA1c test result can warn individuals to undergo lifestyle changes and thus avoid the associated diseases and conditions such as eye diseases, cardiac problems, kidney abnormalities, nerve damage and stroke.
  • A lower than normal hbA1c test result generally tends to indicate at a current or recent instance of hypoglycemia. Such results are also a very serious matter, because low blood sugar levels can lead to fatalities.
  • Thus one can conclude that an hbA1c test is one of the best ways to determine the blood sugar levels in the body.

The hemoglobin A1c chart and blood sugar levels

The determination of the levels of hemoglobin A1c in the bloodstream goes a long way in assisting a doctor to understand the blood sugar levels present in the body.

The hbA1c test screens the red blood cells to verify the deposition of sugar on them over a period of 120 days that covers their lifespan. This enables the physicians to understand whether or not the patient has been taking care of the body and the blood sugar levels over the past few weeks or months. Due to the close correlation that exists between the hemoglobin A1c levels and the blood sugar levels, the doctor can suggest several easy steps and lifestyle changes that enable the patient to control both of them.

The chart given below is an approximate measure of the correlation between the hemoglobin A1c levels and the blood sugar levels

HbA1c (%) Average Blood Sugar (mg/dL)
5 80
6 120
7 150
8 180
9 210
10 240
11 270
12 300
13 333
14 360


The hemoglobin A1c Test

A blood test is used to determine the values of hemoglobin A1c. Many experts from the field of medicine and various medical associations have recommended an hbA1c test as the primary way to diagnose diabetes.

During an hbA1c test, a sample of blood is taken from the vein in the arm and then sent to laboratories for the determination of hbA1c levels. In case an individual is diagnosed with diabetes, then the doctor may suggest hbA1c tests at regular intervals of three to six months, which usually depend on the type of diabetes that afflicts the individual.

It is essential to bear in mind that people who have underlying medical conditions such as liver diseases, kidney problems and anemia or have undergone heavy blood loss may have influenced hbA1c test results that report false numbers. In addition, there are other risks such as infection, accumulation of blood under the skin, fainting or lightheadedness, etc that can result from blood being drawn from the vein.

Individuals have to be aware of the fact that different laboratories yield different results for hbA1c tests and hence such results need to be verified by the doctor for meaning and content.

However, all of us can be rest assured that hemoglobin A1c test is one of the best ways to monitor and control the blood sugar levels in the body. Thus, regular checkups and monitoring can help diabetic individuals to maintain a healthy lifestyle and diet.
