What is the function of HbA1c?

Hemoglobin is the part of your red blood cells that carries oxygen from your lungs to the rest of your body. An HbA1c test shows what the average amount of glucose attached to hemoglobin has been over the past three months. It’s a three-month average because that’s typically how long a red blood cell lives.

How HbA1c is calculated?

You can also use the formula directly, using a calculator: 28.7 x HbA1c — 46.7 = eAG (in mg/dl). For example, an HbA1c level of 7% would translate into 28.7 x 7 — 46.7, or roughly 154 mg/dl. To read more about the HbA1c test, go to www.diabetesselfmanagement.com/2/A1c.

Is HbA1c a fasting test?

Because it doesn’t require fasting, the test can be given at any time as part of an overall blood screening. The A1C test is also known as the hemoglobin A1c test or HbA1c test. Other names for the test include the glycosylated hemoglobin test, glycohemoglobin test, glycated hemoglobin test, or A1C.

What is the difference between glucose test and HbA1c?

The HbA1c develops when haemoglobin, a protein within red blood cells that carries oxygen throughout your body, joins with glucose in the blood, becoming ‘glycated’. For people with diabetes this is important because the higher the HbA1c, the greater risk of developing diabetes related complications.

What is the difference between HbA1c and blood sugar?

What is the difference between fasting blood sugar and HbA1c?

The association of HbA1c with FBS was relatively strong particularly in diabetic subjects. Generally, FBS was a more accurate predictor for HbA1c compared with HbA1c as a predictor of FBS. Although the optimum cutoff point of HbA1c was >6.15%, its precision was comparable with the conventional cutoff point of >6%.

Which is the best test for diabetes?

Health care professionals most often use the fasting plasma glucose (FPG) test or the A1C test to diagnose diabetes.
