We read with great interest the study by Hall et al. [1] in this Journal, reporting on the suitability of dried blood spots (DBS) for HbA1c monitoring. The authors concluded that clinically acceptable HbA1c results could be obtained from home-prepared DBS (using the HemaSpot device), after applying a linear calibration model to adjust the results. As proponents of the deployment of DBS-based applications, we consider it essential for the future of DBS analysis that data in this way are assessed critically. We feel that the authors have not entirely succeeded in this, for several reasons.
