[Glucose analysis in general practice. An examination of 4 instruments designed for general practice and...

Several examinations have shown that the analysis of glucose in primary health care is of poor quality. The reason could be the quality of the instruments and/or the way the instruments are operated. We have examined Glucometer II, Glucochek SC, Reflolux II and Hypocount GA. These instruments were studied both in general practice and at Haukeland Hospital. The test results were compared with the routine used in the hospital laboratory. There were no major analytical differences between the instruments. All the instruments were found to have an analytical quality lower than what is recommended by the Norwegian Quality Control. The requested analytical quality for the instrument depends on the clinical needs. We would recommend that these glucose instruments be used to diagnose acute hypo/hyperglucemia and to some extent in control of diabetes. For a certain diagnosis of diabetes, the use of a more precise instrument is to be preferred. The need for a Quality Control program for glucose measurement in primary health care is emphasized.
