What is the relationship between hba1c and fasting glucose

Hi
What is the relationship between hba1c and fasting glucose ?
Hba1c can be calculated through fasting glucose ?

There is no relationship, and HbA1c cannot be calculated through fasting glucose.

The HbA1c is a sort of average of blood glucose over the previous few months, which will include glucose levels at all times of the day, fasting, after eating, and so on. So all the highs and lows will be included, and we are normally high after we have eaten.
The fasting glucose is just that - fasting levels.

Thanks my lady @Bluetit1802
I was wrong because I thought Hba1c was the one who controlled fasting glucose

This explains what the HbA1c is

But a very high fasting glucose is always related to a high HbA1c. Once the HbA1c stops being "very high" and becomes "high" it is more related to the 2hr post meal BG.

In real life, it is the 2hr post meal BG we care about, as that is what we have control over with our diets.

I am 35 y old , As i am Using Hapibar 60 Mg from last 4 years . So i did HBA1C test which came 5.10 % .
OGTT non Gyne test report show on fasting =108 mg/dl after 1 hour =186 Mg/dl after 2 hours =179 Mg/dl .
so i want to know that i have Diabetes or Pre diabetes or not

I don't think you have it with an A1C of 5.1%, but I have no idea what Hapibar is. As for A1C and fasting glucose I test my blood sugar generally 4X/d: first thing in AM, before lunch, dinner, and bedtime. I don't test 2 hours after meals for "spikes". I have no good reason to mess with that. My average on my meter is usually 5-6. My A1C is consistently about 6-6.5%. It does correlate in my case.

The Hba1c is perfectly normal.

When a normal level of hba1c means I control the level of diabetes ?

I think the problem is in the amount of carbohydrates
