A labile form of hemoglobin A1c is higher in African‐American youth with type 1 diabetes compared to Caucasian patients at similar glucose levels

Abstract

Hemoglobin A1c (HbA1c) levels are higher in African‐American (AA) individuals compared to Caucasians (EA) even after adjustment for blood glucose levels. To better understand the mechanism of this disparity we examined the relationship of an unstable (labile) form of HbA1c (L‐HbA1c) with race and glucose.
