[Comparison of 3 latest-generation glucose micro-reflectometers]. 
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.
