目的了解和探讨孕妇缺铁性贫血与红细胞平均体积(MCV)、红细胞分布宽度(RDW)、血清铁蛋白(SF)检测对妊娠合并缺铁性贫血的相关性及诊断价值。方法采用血细胞分析仪测定MCV和RDW,采用电化学发光仪测定血清铁蛋白,并对结果进行相关统计学分析。结果RDW、SF中度贫血组与正常对照组比较有显著性差异(P(0.05),两贫血组与正常对照组比较有显著性差异(P(0.05)。SF测定缺铁性贫血的敏感性达88.4%,3项联合检测的敏感性高达96.6%。结论孕妇在妊娠中期检测SF是铁营养状态监测的一个敏感指标,而MCV、RDW、SF三项联合检测能显著提高缺铁性贫血的诊断率。
Objective To understand and explore the correlation and diagnostic value between iron deficiency anemia in pregnant women and the average volume of red blood cells (MCV), distribution width of red blood cells (RDW), serum ferritin (SF) in pregnant women with iron deficiency anemia. Methods MCV and RDW were determined by hematology analyzer. Serum ferritin was determined by electrochemiluminescence analyzer. Statistical analysis was made on the results. Results There was a significant difference between RDW and SF moderate anemia group and normal control group (P <0.05), and there was significant difference between the two anemia groups and normal control group (P <0.05) .SF was used to determine the sensitivity of iron deficiency anemia Up to 88.4%, and the sensitivity of the three combined tests was up to 96.6% .Conclusion Detection of SF in pregnant women in the second trimester of pregnancy is a sensitive indicator of iron nutrition status monitoring, and MCV, RDW, SF three joint detection can significantly improve the iron deficiency anemia Diagnostic rate.
