H b A 1 c is a standard clinical assessment of glycemia and the basis of most data relating glycemic control to complications. While daily blood glucose testing gives a picture of day-to-day fluctuations, the H b A 1 c test offers an overview of how well glucose has been controlled over the past 4 months. I devised an innovative mathematical model to describe novel equations governing H b A 1 c which enables analysis of H b A 1 c behavior and provides emerging new concepts in assessment of diabetes management. Linear relationship of H b A 1 c and mean plasma glucose along with the kinetic analysis of H b A 1 c formation has been used as the basic suppositions to construct this model. The main application of this devised model is prediction of mean plasma glucose at any desired point in time after a change in therapy and with great certainty. This model also appraises the pattern of H b A 1 c changes over time and provides a unique opportunity to address common mistakes and misconceptions in routine application of H b A 1 c that could have potentially important implications on diabetes control.
