People who have diabetes should regularly monitor their blood glucose levels so as to prevent extreme fluctuations in the levels. Usually diabetics prefer blood or urine tests to keep a check. These tests are reliable and accurate but they don’t provide any details of past medical history. Urine and blood tests will give levels of only of that moment. The levels might vary depending upon the timing. For example, blood sugar levels might be high after a meal and less during fasting.

Haemoglobin A1C test or HbA1C test is one of the accurate and popular way to monitor diabetes. This test measures the amount of haemoglobin in our blood which has glucose attached to it. This type of haemoglobin is called glycated or glycosylated haemoglobin. HbA1C test is more accurate as it shows  the history of the past 3 months. This is because the haemoglobin cells have a lifespan of three months.

Below mentioned table shows the range of HbA1C levels which can be used to detect the onset or presence of diabetes in any individual.

HbA1C level

Indication of Diabetes

Less than or equal to 5.6%

Normal or no diabetes

5.7% - 6.4%


6.5% and above

Presence of Diabetes

For overall monitoring of diabetes, a diabetic person must get HbA1C test done, twice a year. Any associated medical condition along with diabetes, like kidney disease, liver disorders or anaemia might affect the accuracy of HbA1C test result. Therefore, careful monitoring under medical supervision is recommended.

Elevated levels of HbA1C  is associated with increased risk of many disorders like cardiovascular disorders, heart stroke, renal damage, nerve damage, loss of vision, numbness and weak immunity. Therefore, it is necessary to get yourself regularly monitored.

HbA1C test is a good way of monitoring blood sugar levels. In order to prevent the levels from increasing, one should maintain an active lifestyle. Consume proper diet and refrain from using products which are high in sugar, salt and refined based.
