  • To determine whether you have prediabetes or diabetes

Also known as the HbA blood test, it gives you a detailed diabetic reading of the past three months.

Generally, doctors ask you to undergo this test to see the stability of the glucose level in your blood. Further, this test also helps to determine type 2 diabetes at the initial stage. Some of the common scientific names for this HbA1C blood test are as follows:

Performing the HbA1C test

‘Do I need to fast for the test?’ – this is a very common question that most people ask, especially when doctors tell them to conduct any blood test. Generally, the purpose of fasting is to help you with an accurate test result.
