摘要
目的用诊断试验的方法对网织血小板(RP)和血小板表面相关抗体(PAIgG)的检测,诊断特发性血小板减少性紫癜(ITP)进行评价。方法用流式细胞仪检测61例ITP患者、61例非ITP患者网织血小板和血小板表面相关抗体,后利用诊断试验评价指标进行评价。其中,非ITP患者中,再生障碍性贫血(AA)20例,骨髓增生异常综合症(MDS)21例,急性白血病(AL)20例。结果利用RP%升高来诊断ITP的灵敏度(Sn)0.77,特异度(Sp)0.72,阳性预测值(+PV)0.73,阴性预测值(-PV)0.76,符合率(RA)0.75,KaPPa值(K)0.50,阳性似然比(+LR)2.75,阴性似然比(-LR)0.32;利用PAIgG抗体(+)来诊断ITP的灵敏度(Sn)0.66,特异度(Sp)0.74,阳性预测值(+PV)0.71,阴性预测值(-PV)0.68,符合率(RA)0.70,KaPPa值(K)0.42,阳性似然比(+LR)2.54,阴性似然比(-LR)0.46。RP%的ROC曲线下面积比PAIgG的ROC曲线下的面积大。结论RP%检测和PAIgG检测对诊断ITP有一定的价值,根据需要联合检测意义更大。
Objective To evaluate the method of using the diagnostic test to detect the reticulated platelet (RP) and platelet associated antibody(PAIgG) to diagnosis of idiopathic thrombocytopenic purpura(ITP).Methods A total of 61 idiopathic thrombocytopenic purpura patients and 61 no idiopathic thrombocytopenic purpura patients were included. Among the no idiopathic thrombocytopenic purpura patients,20 patients are aplastic anemia (AA),20 are acute leukemia (AL) and 20 are myelodysplastic syndrome(MDS).PAIgG and per...
