Why testing for HbA1c is needed to control diabetes

The HbA1c test is used to tell the doctor how much a person's average blood sugar has over the past 2 to 3 months.

1. What is HbA1C?

Hemoglobin is a protein found in red blood cells that produces red blood and is responsible for carrying oxygen throughout the body.
The sugar in the blood is called glucose . When glucose is in your blood, it binds to hemoglobin in red blood cells. HbA1c test (English name is hemoglobin A1c test) is done to measure the amount of glucose attached to Hemoglobin.
Red blood cells live for about 3 months, so the test shows the average level of glucose in the patient's blood over the past 3 months. If blood glucose levels have been high in recent weeks, the HbA1c test will be higher.
Too much sugar in the blood damages blood vessels and leads to many serious problems in parts of the body such as eyes and legs.
