本文探讨１５５例中晚期孕妇七项红细胞系统的参数，并与未孕健康育龄妇女比较。结果表明，Ｈｂ１００～１０９ｇ／Ｌ孕妇组与Ｈｂ９０～９９ｇ／Ｌ孕妇组的ＲＢＣ、ＭＣＶ、ＭＣＨ、ＭＣＨＣ、ＲＤＷ－ＣＶ间无显著性差异（Ｐ＞０．０５）。每组部有近半孕妇属于小细胞不均一性贫血，与Ｈｂ１１０～１１９ｇ／Ｌ组及未孕组比较差异非常显著（Ｐ＜０．０１）。孕妇的ＨＣＴ与Ｈｂ呈高度显著正相关（ｒ＝０．９９２），但贫血较轻时ＲＢＣ可正常。因此，妊娠期贫血诊断参数宜选用Ｈｂ或ＨＣＴ，不宜选用ＲＢＣ。诊断标准选用Ｈｂ＜１１０ｇ／Ｌ较理想。
This article discusses the 155 cases of mid-late pregnant women, seven of the parameters of red blood cells system, and healthy women of childbearing age were compared. The results showed that there was no significant difference in the RBC, MCV, MCH, MCHC and RDW-CV between Hb100 ~ 109g / L pregnant women and Hb90 ~ 99g / L pregnant women (P> 0.05). Nearly half of pregnant women in each group belonged to small cell heterogeneous anemia, which was significantly different from that of Hb110 ~ 119g / L group and non-pregnant group (P <0.01). HCT in pregnant women showed a highly significant positive correlation with Hb (r = 0.992), but RBC was normal when anemia was mild. Therefore, the diagnosis of anemia of pregnancy parameters should choose Hb or HCT, should not use RBC. Hb <110g / L is the ideal diagnostic criteria.
