Prediction of near‐future glycated hemoglobin levels using glycated albumin levels before and after treatment for diabetes

Aims/Introduction: In the present study, whether near‐future glycated hemoglobin (A1C) levels could be predicted by changes in glycated albumin (GA) levels before and after treatment for diabetes was investigated. Materials and Methods: After starting diabetes treatment, GA and A1C levels are assumed to change exponentially. From this assumption, the equation for predicting near‐future GA and A1C levels was derived. A total of 54 patients with type 2 diabetes mellitus in whom diabetes treatment was initiated or altered were enrolled. By incorporating GA and A1C values before and 2–4 weeks after starting treatment (second visit) into the equation, the predicted GA and A1C levels at the third visit (5–7 weeks after treatment) were obtained. Results: A strong and positive correlation was observed between predicted GA and measured GA at the third visit (R = 0.669, P
