A comparative analysis of testing results of blood-glucose on 21 POCT glucose meters and automatic biochemical analyzer

Objective To regularly monitor the identity of the testing results between the hospital′s 21 POCT glucose meters and the Beckman biochemical analyzer,to obtain an overall understanding of differences in blood-glucose testing values in the hospital.Methods 10 patients whose fasting blood-glucose were between 3.76 mmol/L and 19.84 mmol/L(results from the biochemical analyzer) were selected,and EDTA Anticoagulant whole blood and non anticoagulant blood were drew.The former was put on POCT glucose meter to detect its blood-glucose,and the latter was put on the Beckman biochemical analyzer to detect its serum glucose.Each blood sample was tested for three times and taken the mean values,The acceptable POCT glucose meters were numbered according to service years.5 POCT glucose meters were selected randomly,the samples were detected from xin jiang central of clinical laboratory,they were compared with the target values in the EQA report and calculate bias.Results The bias of 19 glucose meters were between 0.93% and 11.49%,and the bias of 2 glucose meters were larger than 20%.The coefficients of variation of the 19 glucose meters ranged between 3.14% and 10.82%.The bias of five glucose meters were between 0 and 6.87% according to POCT glucose EQA target values in xinjiang clinical laboratory center.Conclusion The testing results of 19 glucose meters are identical with the biochemical analyzer,2 glucose meters have a sensible difference.The testing results of the biochemical analyzer are 0.94% to 12.98%,these were higher than the Glucose meters.The bias of the testing results between the five sample POCT glucose meters and the target values were up to the quality assessment standards of xin jiang clinical laboratory center.
