Comparison of dextrostix/reflectance meter and auto-analyser methods of blood glucose determination
A study was undertaken to assess the accuracy of a new Dextrostix/Reflectance Meter system for rapid blood glucose determinations over a wide range of values, in 390 consecutive patients attending a busy diabetic clinic. In each case a simultaneous comparison with the ferricyanide reduction method on the auto-analyser was made. While a good correlation existed between the two methods for blood glucose values below 200 mg/100 ml, above this level significant discrepancies became apparent. Reasons for this are briefly considered and practical applications of the findings are discussed.
