The comparison test and quality management of POCT blood glucose meters

Objective To regularly monitor point of care testing(POCT)blood glucose meter and the biochemical analyzer glucose determination results consistency,and to learn the quality of POCT blood glucose meter and regulate management.Methods Fresh EDTA anticoagulation whole blood was used to analyze the test results between the 25 machines POCT blood glucose meters and biochemical analyzer.Results The CV of the high,medium value samples tested by POCT was 1.70%-5.74%,and the standard deviation result of the low sample was 0.16-0.39 mmol/L accord with the country′s measurement repeatability requirements of blood sugar test system.Compared with biochemical analyzer,the testing results of 5 samples by using POCT were less than biochemical analyzer.Deviations corresponded with glucose POCT accuracy requirements of the U.S.clinical laboratory standardization committee.Conclusion The test result of POCT blood glucose meter is credible.Personnel training and quality management are important measures to ensure the test quality of POCT.
