Assessment of time to glucose peak during an oral glucose tolerance test

Abstract

We read with interest the article from Chung et al. on the association between time to glucose peak and prediabetes.¹ We agree with the authors in that the morphology of the glucose curve is worth investigating as an additional indicator of prediabetes and diabetes risk. This is a rather well studied topic in the literature, and most authors agree that adding an intermediate glucose measurement (at 30 or 60 minutes) improves the ability to identify subgroups with forms of dysglycaemia not picked up by the traditional guidelines based on fasting and 2-hour values.
