Evaluation of a new blood glucose reflectance meter and comparison with visually interpreted strips

The utility of a new glucose reflectance meter (the Reflolux; Boehringer Mannheim) and the accuracy of visually interpreted strips (Haemo-Glukotest 20-800R; Boehringer Mannheim) for the determination of blood glucose levels were assessed in a study of 50 insulin-dependent diabetics who regularly used the strips for home monitoring of their blood glucose levels. There was a highly significant correlation (r = 0,970, P less than 0,0001) between readings on the meter and results of a laboratory reference plasma glucose determination method. The patients' visual assessment of their blood glucose levels using the strips also correlated with the results of a reference method in 44 cases (88%), especially at levels below 11 mmol/l (r = 0,944, P less than 0,0001). However, readings from 6 patients were inaccurate, despite the fact that these patients regularly used the strips. A patient's ability to use the strips should be properly evaluated before it is recommended that they be used for monitoring of blood glucose levels at home. Reflectance meters are not usually necessary for satisfactory blood glucose monitoring at home. This meter may prove useful in training patients to read blood glucose assessment strips accurately, and is suitable for hospital or office use.
