摘要 目的应用SYSMEXXE-2100全自动血细胞分析仪定量检测外周血网织血小板比率(IPF),探讨IPF对血小板减少性疾病的诊断价值及疗效观察。方法选取IPF中、低值与高、中、低值质控品检测CV评价批内、批间精密度及稳定性。选取原发性血小板减少性紫癜(ITP)134例,ITP缓解组16例,再生障碍性贫血(AA)36例,骨髓增生异常综合征(MDS)19例及377例对照组,5例ITP住院病人动态,检测批内IPF值。结果本实验室检测IPF中、低值的批内CV分别为4.9%和6.2%,批间CV分别为3.3%、3.9%、3.6%;稳定性试验8小时内CV为5.4%,36小时内CV为16.2%。ITP组IPF中位数为8.6%,ITP缓解组组为5.6%,AA组为4.3%,MDS组为6.8%,健康对照组为2.7%,男女无差别(P】0.05)。健康组、AA组和ITP缓解组组间无显著性差异(P】0.05),ITP组和MDS组间无明显差异(P】0.05),以健康组、AA组作为IPF%正常/减低组,ITP组和MDS组作为IPF%升高组,正常/减低组和升高组间均存在显著性差异(P【0.05)。MPV仅ITP组显著高于健康组(P【0.05),IPF绝对值(IPF#)MDS组、AA组和ITP组低于健康组(P【0.05)。动态监测ITP治疗有效病人IPF#和PLT均显著升高,IPF显著下降(P【0.05)。结论检测IPF值有助于血小板减少性疾病病因学诊断,同时也可作为疗效观察指标。
