Brief Answer:
About HbA1c;

Detailed Answer:
Hello and thank you for asking!

For people without diabetes, the normal range for the hemoglobin A1c level is between 4% and 5.6%.
Hemoglobin A1c levels between 5.7% and 6.4% mean you have a higher chance of getting diabetes (prediabetes) while the value of 6.5% or higher mean you have diabetes.

Anyway, fasting and postprandial levels are also needed for a better diagnosis as fasting or postprandial glucose levels may be higher than normal and HbA1c within the normal ranges due to low glucose levels during the day.

So the three components are helpful in making the diagnosis.

Hope to have been helpful. Let me know if I can assist you further.

Kind regards,
Dr.Mirjeta
