HbA1C is a one dimensional linear measure. The standard oral glucose
tolerance test has two dimensions, that is fasting glucose and two hour
glucose.
A one dimensional descriptor cannot describe a two dimensional entity
because it contains less information and therefore HbA1C cannot replace
the oral glucose tolerance test.
