Danish general practitioners (GPs) perform glucose measurements as a part of the traditional monitoring of glycemic control in patients with diabetes, and for diagnostic purposes. The number of glucose tests corresponds to 10% of all tests performed in GP offices, exceeded only by hemoglobin tests. On average, each GP office performs 350 blood glucose (B-glucose) measurements per year. At present, there are no recommendations in Denmark concerning relevant use of B-glucose analysis and no quality demands, in contrast to US practice . The introduction of a variety of different small instruments for performing near-patient testing in primary healthcare has revealed problems regarding quality assessment, quality assurance, and documentation.
