ROLE of GTT and HbA1c

HbA1c levels have been validated in the diagnosis of diabetes. They have not been adequately validated in the estimation of cardiovascular disease risk, and cannot determine IFG and IGT, where elevated CVD risk also needs to be considered.
For this reason, GTT remains the risk stratification tool where there is non-diabetic hyperglycaemia.
