Multicentre evaluation of the EBIO plus glucose analyser.

The EBIO plus, a newly developed dedicated glucose analyser, was tested at three different sites for its analytical characteristics and practicability; Results were linear over a range of 2-50 mmol/l, precision was satisfactory (overall CV < 5.3% at a concentration level of 1.8 mmol/l and < 3.7% at a concentration level of 4.5-21 mmol/l). Calibration was stable up to 90 minutes. No significant influences were observed for several potential interfering substances at physiological or therapeutical levels. Practicability was found to be good. Sample throughput depends on calibration frequency and is maximally 166 per hour. Some problems with outliers had to be overcome in the beginning of the evaluation period, but in the end all evaluators concluded that the EBIO plus is user friendly with good analytical characteristics.
