Abstract:
Objective To evaluate the influence of hematocrit(HCT),vitamin C(Vc)and galactose on three portable blood glucose meters to provide some reference for clinical selection of appropriate blood glucose me-ter.Methods 20 heparin anticoagulant venous blood samples in the clinical laboratory department of Nanfang Hospital were selected for verifying the accuracy of blood glucose meter.2 healthy volunteers were selected for collecting 5 w hole blood samples in interferent test.Referring to the detection results of Roche automatic bio-chemical analyzer,the Nova StatStrip Xpress glucometer,Bayer Contour Plus glucometer and Roche Accu-chek Performa blood glucose meter were performed the accuracy verification.The influence of HCT,Vc and galac-tose on the detection results of above three portable blood glucose meters were evaluated.Results The detec-tion accuracy of Nova StatStrip Xpress and the Roche Accu-Chek glucometers all conformed to the require-ments of ISO15197:2013 standards.The detection accuracy of Bayer Contour Plus glucometer only conformed to the requirements of ISO15197:2003 standards.Under the interference of different levels of HCT,Vc and galactose,the detection results of Nova StatStrip Xpress glucometer conformed to the requirements of ISO15197:2013 standards;w hen detecting low concentration of blood glucose,the Bayer Contour Plus glucom-eter was interfered by 10 mg/dL Vc,and other detection results conformed to the requirements of ISO15197:2003 standards;the anti-interference performance of Roche Accu-chek Performa glucometer conformed to the
