Glycosylated or glycated haemoglobin

As we all know, haemoglobin is the part of red blood cells that carries oxygen from lungs to different body cells. One of the parts of haemoglobin binds to glucose present in the blood named as glycosylated haemoglobin.

It is commonly known as HbA1c.

It is the measure used to identify the three months average blood glucose levels of a diabetic person. The glucose present in the blood stream gets attached to haemoglobin for the life of red blood cells which is usually 120 days or 4 months.

In diabetics, it is recommended to get the glycosylated haemoglobin checked every 3-6 months, as it shows your diabetes control over past 3 months.

A simple blood test is done in a laboratory to get your HbA1c levels tested.

A higher level of HbA1c shows a poor control over diabetes, which means more glucose is attached to haemoglobin.

Better results of glycosylated haemoglobin reduces risks of early onset of diabetes related complications like retinopathy, cardiovascular complications, nephropathy, neuropathy etc.

HbA1c Results-

Non-diabetic- 6%

Prediabetes- 6 – 6.5%

Diabetic- > 6.5%
