A new combination reflectance meter/visually interpretable system (Glucometer II®/Glucostix®, Ames Division, Miles Laboratories, Elkhart, IN) has been designed for self blood glucose monitoring. Performance evaluation of this system demonstrates a linear relationship between meter-determined blood glucose values and laboratory-determined whole blood glucose values (y = 0.95x + 2.86, r = 0.97). In addition, 95% of visually interpreted blood glucose values are within one color block of YSI comparative values. Error grid analysis, a new method for determining the clinical accuracy of patient-determined blood glucose results, demonstrated that components of this new system produce clinically accurate blood glucose results.
