HbA1C - நீரிழிவு நோயை கண்டறிய HbA1C பரிசோதனை ஏன் செய்யப்படுகிறது?

HBA1C - Definition - Easy and Quick Reference



The term HbA1c refers to glycated haemoglobin. It develops when haemoglobi, 

a protein within red blood cells that carries oxygen throughout your body, 

joins with glucose in the blood, becoming ‘glycated’.By measuring glycated haemoglobin (HbA1c), 

clinicians are able to get an overall picture of what our average blood sugar levels 

have been over a period of weeks/months.



For people with diabetes this is important as the higher the HbA1c, 

the greater the risk of developing diabetes-related complications.



HbA1c is also referred to as haemoglobin A1c or simply A1c.



Normal Levels of Hemoglobin A1c 

In healthy people, the HbA1c level is less than 6% of total hemoglobin. 

A level of 6.5% signals that diabetes is present. 

Studies have demonstrated that the complications of diabetes can be delayed or 

prevented if the HbA1c level can be kept below 7%. It is recommended that treatment of diabetes be 

directed at keeping an individual's HbA1c level as close to normal as possible (<6%) without episodes of 

hypoglycemia (low blood glucose levels).



HbA1c Levels





Normal Below 5.7 %

Prediabetes 5.7% to 6.4%

Diabetes 6.5% or greater
