Abstract

Abstract: Background: Erythrocyte parameter analysis is the important means for diagnosis and treatment of hematological diseases, which are essential for screening of thalassemia in southern China combined with hemoglobin electrophoresis analysis. But little is known regarding the reference intervals (RIs) in healthy pediatrics in these two areas. Methods: 95% RIs of erythrocyte parameters were calculated from 853 healthy preschoolers, aged from 1 days to <6 years, according to the C28‐A3C guidelines of the Institute of Clinical and Laboratory Standards. To express the magnitude of sex and age variation, standard deviation ratio (SDR) was calculated using ANOVA. Concurrently, we selected 3814 thalassemia carriers as carriers group and drew receiver operating characteristic (ROC) curves to establish the optimal cut‐off values of hemoglobin electrophoresis parameters, which were used as the upper/lower limits of RIs to efficiently screen thalassemia. Results: All parameters except red blood cell (RBC) required age partitioning, confirmed by SDRage above .4. There was no need for sex partitioning on all parameters, confirmed by SDRsex below .4. The optimal cut‐off value of Hemoglobin A2 (Hb A2) in the four subgroups was <7.8% (Hb A), 2.3%–3.2%, 2.5%–3.6% and 2.6%–3.6%, respectively. Conclusion: In this study, the establishment of RIs improved the diagnostic efficiency of hematological disease (especially thalassaemia) for children in Guangxi. It provides reliable hematological references for the identification and diagnosis, treatment monitoring, and health screening of children's clinical diseases.
