Type 2 diabetes means your blood sugar stays too high over time, and doctors check this with two tests: one after you've fasted and another called HbA1c that shows how much sugar has been sticking to your red blood cells over the past few months.

The study shows that even when blood sugar is high, the HbA1c test can appear normal if something affects red blood cells, which supports the idea that HbA1c measures sugar damage over time in red blood cells.
Plasma glucose and HbA1c discrepancy may indicate hemoglobinopathy: a case series
The study shows that HbA1c usually reflects blood sugar levels over time, but sometimes gives wrong results due to blood conditions, so doctors should use both HbA1c and blood sugar tests. This supports the idea that both tests are important for diagnosing diabetes.
