RESUMO
Three glucose reflectance meters (Reflolux II = Accu-Chek II, Glucometer II and Hypocount GA) were tested for precision and accuracy when used by medical personnel of a diabetic outpatient department and for self-monitoring at home. In addition, the visual readability of the appropriate reagent strip was checked. All three systems were sufficiently valid for reflectometric reading, while visual evaluation showed a higher deviation. The precision of Accu-Chek II under optimal conditions in the outpatient department was comparable to the precision of laboratory examinations (CV 3.3%). When used by patients themselves, Accu-Chek II and Glucometer II were sufficiently precise (CV 4.8% [corrected] and 5.3% respectively). These devices are recommended for blood glucose self-monitoring.
