Abstract:
Objective To evaluate the results of 2017 external quality assessment for newborn hemoglobinopathyand improve the quality of disease screening .Methods Each of 26 participating laboratories testing newborn hemoglobinopathy across the country received 5 batches of quality control blood spots ( Lot 201711-201715 ) in octorber 2017.Laboratories voluntarily participated in the survey and reported the results, methods, equipments and reagents information .Clinet EQA, and Microsoft Excel 2010 were used to perform statistical analysis on the laboratory test results .The rates of accuracy ( number of correct results/total number of submitted results ) were used for evaluating the performance of laboratories . Results 24 laboratories submitted the testing results with a return rate of 80.8%(21/26).The rates of accuracy for each lot were 100%(21/21), 90.5%(19/21), 90.5%(19/21), 57.1%(12/21) and 100%(21/21 ) respectively.Conclusions The results of this external quality assessment for newborn hemoglobinopathy is generally satisfactory , except for HbBarts′and HbA2.The screening laboratories should improve their quality control system , take timely measures to correct mistakes during the analytic period and improve the accuracy of screening tests for newborn hemoglobinopathy.
