His pre-prandial plasma glucose (before lunch and before dinner) should be measured.

The glycosylated hemoglobin (HbA1c) value is a net reflection of the plasma glucose values in the fasting and postprandial states. Preprandial glucose values (before breakfast, before lunch and before dinner) are a reflection of the fasting state while two-hour post meal values are a reflection of the postprandial state.

When the glycosylated hemoglobin value is high but the fasting (pre-breakfast) glucose value is normal, we should first check the preprandial glucose values before lunch and before dinner. If these are normal, then we can assume that the postprandial values are high and proceed to check the plasma glucose two hours after meals. If the preprandial values are high, it is better to target therapy to ensure that these are well controlled before checking the postprandial glucose values.
