CLINICAL USEFULNESS OF A NON-WIPING TYPE GLUCOSE METER IN DIABETIC-PATIENTS

A non-wiping type glucose meter using electrochemistry was developed. The glucose sensor strip has a sophisticated micro-structure for aspir ating blood automatically. The meter compensates for drift of sensor o utput due to temperature change of the atmosphere. Mounting blood on t he sensing site and wiping blood and precise time are no longer requir ed. Range of measurement is 40-500 mg/dl. Reading of the meter for sta ndard solutions of 90 or 360 mg/dl glucose showed negligible drift of measurement from 10.5-degrees-C to 38.5-degrees-C. The correlation bet ween plasma glucose concentrations as determined by the meter and that by a Glucose Analyzer 2 was 0.995 with a slope of 1.00 and intercept of -0.65 (n = 48). In the case of blood glucose concentration (Y), the values were Y = 1.06X - 0.9 1, r = 0.987, n = 62. This meter is quite easy to use and is highly accurate for glucose monitoring in patients regardless of operation skill. It should thus be readily applicable t o diabetic patients.
