Analysis: Investigating the quality of POCT devices for HbA1c, what are our next steps?

There are a growing number of publications evaluating the performance of HbA1c point-of-care testing (POCT) devices when compared to routine laboratory instruments, but is this what we need from future studies? Here we describe the current understanding of the performance of POCT for HbA1c, which areas need further studies, and the key requirements for future publications based on performance evaluations of these devices. These include studies in clinical settings, performance measured against internationally standardized reference methods, and the need to evaluate new to the market devices that do not currently have a detailed performance history. In addition we highlight the need for external quality assessment schemes that are designed to support POCT in a wide range of clinical settings.
