小红细胞

目的：探讨用血液分析仪作血常规检测时由非小红细胞引起的上限区域干扰（upperregioninterference，URI）对血小板计数（BPC）结果的影响。

Objective : To investigate the influence of upper region interference ( URI ) flag due to other than microcyte on blood platelet count in automated hematologic analyzer .

方法：用血液分析仪作血小板参数分析，对出现URI报警但又不是小红细胞干扰的标本作显微镜计数，把两法结果作配对t检验。

Methods : Automated hematologic analyzer was used for platelet count if the URI flag was not due to the effect of microcyte , these samples were also counted under light microscope , and the results of these 2 methods were calculated for t test .

结果表明，仔猪在断奶后一段时间，处于营养缺乏性单纯小红细胞性贫血状态。

The results showed that piglets were in the condition of small RBC anaemia of nutrition deficiency at some time after weaning .

结论有小红细胞的异常标本，二维激光散射法优于电阻抗法血液分析仪计数血小板。

Conclusion The two-dimensional laser light scattering method is superior to the impedance method when the abnormal sample with small red blood cells was detected .
