Glycosylated Hemoglobin Blood Test

A glycosylated hemoglobin test is used to measure the amount of blood sugar (glucose) around hemoglobin. Hemoglobin is a component of the blood’s red cells that carries oxygen from the lungs to the rest of the body.

The importance of a glycosylated hemoglobin test is that it shows the amount of glucose around hemoglobin from the past three months, meaning the entire life of a red blood cell.

London Blood Tests offers a high-class glycosylated hemoglobin blood test. If the blood test result is higher, then it might be a sign of diabetes appearance in your body. Diabetes can lead to serious health issues, including heart disease, kidney disease, nerve damage, and many others.

What is Glycosylated Haemoglobin (HBA1C) and why is it important in our body?

Glycosylated Haemoglobin (HBA1C) is a form of hemoglobin that is linked to sugar. Your body cannot deal with the larger quantity of sugar and the remains stick to blood cells and build up in your blood. If the amount of sugar in your blood is higher than normal it’s more likely to develop diabetes complications.

To be sure of your blood sugar levels, we recommend booking a glycosylated hemoglobin test provided by our clinic, London Blood Tests.
