Glucometers are used to quickly obtain glucose concentrations in the hospital and at home. For quality assurance, the American Diabetes Association recommends periodically comparing the results from glucometers with those from referenced laboratories (1). Usually, measurement using glucometers is done one-by-one by technicians, which is costly regarding manpower. In contrast, measurement using blood analyzers in laboratories saves manpower by analyzing after sufficient samples are collected. Tubes containing glycolytic inhibitors such as sodium fluoride are used to keep the glucose level constant (2). If analyses by glucometers could be …
