![]() The results showed no significant differences between type I and type II diabetic patient responses. Interviews were conducted to derive personal reference values and significant deviations from these values for the limit of hypoglycemia, the limit of hyperglycemia, and the upper and lower limits of acceptable blood glucose for physicians and patients with diabetes at the Park Nicollet Medical Center, Minneapolis, Minnesota.įifty patients with diabetes (30 type I and 20 type II), and 43 physicians (14 endocrinologists, 14 family practitioners, and 15 general internists) were enrolled in the study. The study’s objective was to determine the maximum analytical error that is allowable in portable whole blood glucose meters. Measurements of comparisons with glucometers should be carried out only with devices, which produce corresponding results. As sample material can be used - with some exceptions - also NaF-EDTA or EDTA-stabilized venous blood. Therefore measurements of glucose with many glucometers still have estimating character. We conclude that a significant proportion of data produced with glucometers deviate by more than 15% from reference methods. In other cases, glucometers produced results which were significantly different from those obtained with the reference method. Measurement of glucose in EDTA-blood with Accutrend alpha, One touch II, One touch basic, Medisense Card sensor /Pen sensor/ Precision QID with-sensor QID plus produced results of which 87-97% were within the ☑5% range of the reference method. ![]() Upon determination in NaF-EDTA-blood with some glucometers (Accutrend alpha, Medisense Card sensor, Accutrend GC, Accutrend sensor) > 90% of the results were within the ☑5%-range of the reference method. Determination of glucose with the glucose-oxidase-method with the ESAT 66602/ECA 2000 served as the reference method. We measured glucose levels in NaF-EDTA- or EDTA-stabilized venous blood from 30 patients by the use of the following devices: Accutrend alpha, Accutrend GC, Accutrend sensor, One touch basic, One touch II, Glucometer Elite, Medisense Card sensor, Medisense Precision QID, Medisense Pen sensor, Medisense Precision G. ![]() The maximum deviation of individual results from the reference method could be such a target. The comparability of results requires identical quality standards for glucometers and established laboratory methods. Glucometers for glucose-selfmonitoring are widely used not only by patients and practitioners but also in hospitals. ![]() Intensified insulin therapy requires repeated measurements of blood glucose levels every day. ![]()
