To the Editor,

The letter from Wiwanitkit et al has highlighted the problems that can be encountered in conducting an oral glucose tolerance test (OGTT). However, our article and that of Sharif et al have shown that when only the fasting blood glucose is used, several patients with impaired glucose tolerance (IGT) and new onset diabetes after transplantation (NODAT) are missed. Hence, fasting glucose underestimates the prevalence of NODAT and ignores the prevalence of IGT. These findings suggest that the routine use of an OGTT in renal transplant recipients is a valuable clinical tool to risk- stratify each patient for the development of NODAT and cardiovascular disease.

The problems highlighted by Wiwanitkit et al have to be understood, and they should be over-come while performing the OGTT and during the interpretation of the results of the test.[5]
