The glycated hemoglobin test or HbA1c Test is usually suggested so that the blood sugar levels in your body can be deciphered. This test shows how much glucose has been attached to the body’s haemoglobin over a period of three months. The time frame of three months is taken because that is usually the life span of an RBC in our body. Read on with us to know more about HbA1c test for diabetes diagnosis.
If your body is showing any of the below-mentioned symptoms of HbA1c or diabetes then the doctor may recommend you for an HbA1c Test:
- Increase in the urination tendency
- Feeling excessive thirst
- Vision problems
Usually, if you are overweight, have high blood pressure, high cholesterol and are physically inactive, the doctor might ask you to get an HbA1c Test done.
How the HbA1c Blood Test is conducted
The HbA1c Blood Test entails taking a small blood sample from your arm. This blood sample is then collected in a vial and taken for a test. Being a measure of an average, you do not need to fast before the test. Also, during or after the HbA1c Test, there are no side effects.
Diagnosis of the HbA1c Test
The HbA1c Test diagnosis is usually expressed by HbA1c level in the form of percentages, and HbA1c range have the following implications:
- Below 5.7% – HbA1c Normal range.
- Between 5.7-6.4% – Prediabetes
- Above 6.5% – Diabetes
How does this test work?
HbA1c appears when the haemoglobin is bonded with glucose present in your blood. This process in medical terminology is known as glycation. For a diabetic person, the blood glucose level is obviously going to be high, which is reflected in a proportionate number of blood cells getting glycated. Invariably, the percentage that is expressed in the result is used to conclusively prove whether he/she is suffering from high glucose levels or not.
The HbA1c Test has its own share of limitations. You cannot use its reading to detect gestational diabetes which affects pregnant ladies. The test may be less reliable for children than it is for adults.
In case you have anaemia or any other blood disorder, this test would not be able to generate and give you accurate answers. If that is the situation, your doctor may recommend other tests tailored to your condition.
