Comparability research on blood glucose results among different kinds of detection systems

Objective To discuss the comparability of blood glucose(Glu)results with different detection systems.Methods Six different kinds of biochemistry detection systems were used to detect plasma Glu concentrations at 2 levels of Randox quality controls and 48 clinical plasma according to EP9-A file.The collected data were treated with statistical analysis.Results Analysis of variance showed Glu results from different control and patients plasma had significant difference between various detection systems (P0.001).The correlation coefficiency of each detection system was above 0.975 and their reliability coefficiency was 0.999 3.The CV value of all detection systems did not excell T± 3.3% by precise assessment.Target system l was regarded as standard detection system and evaluated the acceptability of other detection systems.As a result,all detection systems except detection system 2 and detection system 3 did not excel T±5% according to clinical assessment.Conclusion The precision of Glu results in the 6 kinds of detection systems accords with clinical requirement.However,incomparability exists in the evaluation of clinical acceptability.
