摘要
目的对Sysmex XE-2100测定红细胞分布宽度的参考区间进行调查,以建立正确的参考区间。方法依据NCCLS C28-A2指南,筛选参考个体、采集运送标本、检测标本和分析数据,并通过健康体检者结果在参考区间内、外的情况以及RDW-CV和RDW-SD结果符合率的比较对新建的参考区间进行了验证。结果RDW-CV和RDW-SD在正常人群中呈偏态分布,二者在男性和女性中结果无显著性差异,可并用参考区间。合并后的参考区间RDW-CV为<13.9%,RDW-SD为<47.6fl。与厂家提供的参考范围相比,建立新的参考区间后RDW-CV和RDW-SD的符合率得到明显增加。结论新建立的参考区间比厂家提供的参考范围更适合本实验室。
Objective To establish the reference interval of red blood cell distribution width examined by hematology ananlyzer XE-2100. Methods Reference individuals selection, specimen collection and data analysis were accomplished according to the guide of NCCLS C28-A2, and the reference interval was validated by comparing with the coherence of results within and out of the reference interval between RDW-CV and RDW-SD to those of the reference interval offered by manufacturer. Results The results of RDW：-CV or RDW-SD in normal population did not conform to a Gaussian ＇distribution. The results between male and female showed no statistical significance. The up limit of reference interval of RDW-CV was 13.9%, and with 47.6fl of RDW-SD. The coherence increase largely using the new reference interval. Conclusion The new reference interval is more suitable for our laboratory than that offered by manufacturer.
