HbA1c – normal range, chart, blood test values
The Hemoglobin A1c normal range is referred to as the HbA1c normal range. Hemoglobin are the protein molecules which occur in the red blood cells present in the body. One of the key functions of hemoglobin is to supply the oxygen-rich blood from lungs to different tissues and organs in the body, and then take the carbon dioxide back to the lungs.

All of us are aware that sugar has a sticky quality which makes it adhere to any kind of surface. Its elimination from that surface can also be quite arduous. The same rationality can be applied to the body. People with elevated levels of sugar in their bodies usually contain glycated hemoglobin in the bloodstream.

The high sugar levels in the body trigger the excess sugar to bind itself to the hemoglobin, thereby leading to the formation of a coat of sugar on it. Red blood cells typically live for approximately 120 days in the bloodstream. This allows an HbA1c range test to determine the levels of sugar occurring in the body for over the past 3 months.

As compared to regular monitoring of glucose carried out at home, an HbA1c range test is more reliable and relatively better.

The hemoglobin A1c normal range

• A majority of HbA1c tests that are performed to ascertain the normal levels differ from one lab to the other.


• Medical professionals maintain that the HbA1c normal range generally falls between four and six percent. A few other medical experts have stated that the HbA1c levels in diabetic patients should be below seven percent.


• Since HbA1c range tests are used to ascertain the levels of blood sugar, it can act as a helpful tool to prevent the onset of different kinds of health complications that may arise due to an underlying presence of diabetes. An HbA1c test result which is higher than normal can warn patients to make changes in their lifestyle so as to prevent the development of related conditions and diseases like cardiac abnormalities, eye problems, kidney diseases, stroke, and nerve damage.


• An HbA1c test result that is lower than normal often points to the present of a recent or current case of hypoglycemia. It is also a very serious situation, as low levels of blood sugar can result in death of the patient.


• It may also be noted that test results indicating HbA1c readings as over 7 percent is a definite sign of poor maintenance and regulation of diabetes and blood sugar levels over the last few months. In these cases, patients may considerably reduce future instances of micro-vascular risks and complications by taking necessary steps to get the HbA1c levels back within the required normal range.

It is thus safe to say that the HbA1c normal range test is one of the best methods to ascertain the levels of blood sugar in the body.

HbA1c chart and levels of blood sugar

The determination of HbA1clevels in the bloodstream is one of the first steps that a doctor will undertake to gauge the levels of blood sugar in the body.

The HbA1ctest monitors the red blood cells to confirm the accumulation of sugar deposits on them during their lifespan, i.e. about 120 days. This allows a doctor to confirm whether or not the affected individual has followed the essential guidelines to keep the blood sugar levels under control over the last few weeks or months.It may be noted that a close correlation exists between the levels of blood sugar and the HbA1clevels. This allows a physician to recommend many easy-to-follow steps and lifestyle changes that can help a patient to effectively manage both the criteria.

The table detailed below is an estimated measure of the correlation between the levels of blood sugar and HbA1c 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 HbA1c normal range test

• The values of HbA1c are found out via a blood test. A number of medical experts and professionals as well as different medical associations have confirmed the HbA1c test as the best method to diagnose the presence of diabetes.


• An HbA1c test involves removal of a blood sample from the vein in an arm, which is then forwarded to labs for verifying the levels of HbA1c. If a person is diagnosed with diabetes, then the physician may recommend regular HbA1c tests in the future. Depending on the type of diabetes, the patient may need to undergo the HbA1c normal range test after every 3 to 6 months.


• It is also important to note that individuals who have pre-existing medical disorders like kidney anomalies, liver conditions, and anemia; or have experienced heavy blood loss, may produce incorrect HbA1c test results with false numbers. An HbA1c test also comes with other risks such as buildup of blood below the skin, infection, dizziness, fainting, etc. which may be caused due to drawing of blood from the vein.


• Patients have to remember the fact that varied labs offer varying HbA1c normal range test results. Hence, all HbA1c test results have to be checked by a physician for content and evaluation.

It can however be positively concluded that the HbA1c normal range is one of the best ways to screen and manage the levels of blood sugar in the body. Regular visits to a doctor and monitoring can assist diabetic patients to continue a healthy diet and lifestyle.

Treatment of abnormal blood sugar levels

Treatment of diabetes includes oral medications, insulin injections, eating a balanced diet, and maintaining a healthy weight.

• Your diet should consist of whole grains, vegetables, and fruits. Minimize the intake of animal products, sweets, and refined carbohydrates.


• Exercise on a daily basis for at least 30 minutes a day


• Patients affected by type 1 diabetes require insulin therapy for survival. A few type 2 diabetes patients may also need insulin therapy


• Oral medications to stimulate insulin production by pancreas, or to inhibit release of glucose by liver are also given


• Pancreas transplant and bariatric surgery are other treatment options.
