Abstract
Objective: To evaluate the consistency of testing results of blood glucose (Glu) in heparin and EDTA anticoagulated blood specimens between 6 point-of-care testing (POCT) blood glucose meters and the VITROS 250 biochemical analyzer. Methods: The two kinds of anticoagulated blood samples were detected by 6 POCT blood glucose meters and the VITROS 250 biochemical analyzer, respectively. The detection results of POCT blood glucose meters in the two kinds of anticoagulated blood specimens were compared with those by VITROS 250 biochemical analyzer, which act as target value, then to calculate the relative bias. According to general specification in vitro diagnosetic lest systems for blood glucose self-test monitoring system (GB/T19654-2005). when the Glu>4.2 mmol/L or Glu<4.2 mmol/L, the results of relative deviation and absolute deviation were satisfactory and lower than 20% ,0.83 mmol/L, respectively. The detected results of heparin anticoagulated blood samples for each POCT glucose meter were analyzed to determine their correlation with EDTA anticoagulated blood. Results: When the values of glucose were over 4.2 mmol/L, the minimal and maximal deviation of the testing results from the POCT glucosemeters and the VITROS 250 biochemical analyzer was 0.5%, 28.6%, respectively, in heparin anlicoagulaled blood samples. It was 0.2%, 26.8%, respectively, in EDTA anticoagulated blood samples. When the values of glucose were less than 4.2mmol/l.. absolute deviation of the testing results from the POCT glucosemeters and the VITROS 250 biochemical analyzer was less than 0.83mmol/L in two anticoagulated blood samples. The detected results of heparin and EDTA anticoagulated blood had a good correlation and the correlation coefficient was over 0.95 (P<0.01). Conclusion: The testing results of the POCT glucosemeters are not different significantly in heparin and EDTA anlicoagulated blood samples as compared with the VITROS 250 biochemical analyzer.关键词
