I present to you 3 GTTs with corresponding HbA1c performed on fasting samples from yesterday work in our lab in support of above statement:
0h 1h 2h HbA1c GTT interpret.
1. 55 year old man 6.8 14.1 10.5 7.5% IGT
2. 60 year old man 6.3 14.1 12.5 6.2% DM
3. 62 year old man 5.1 11.8 12.8 5.4% DM
Do you think that HbA1c should be given a leading role in diagnosis of IGT/DM and forget about artificial GTTs? A question for WHO experts.
