| 摘 要： | 目的评价Sysmex XE-5000血细胞分析仪对血小板(PLT)的检测性能。方法对XE-5000分别用电阻抗法和荧光法对血小板计数进行精密度、线性测试及干扰试验进行评估,并与显微镜计数法作对比试验。运用SPSS12.0对数据进行分析。结果平均批内精密度为PLT-I 1.30%、PLT-O 1.40%;批间精密度为PLT-I1.87%、PLT-O2.39%;携带污染率范围为PLT-I 0.00%~1.32%、PLT-O0.00%~1.17%;平均为PLT-I 0.44%和PLT-O0.33%;在线性稀释试验中低、中、高值与理论值的相关系数(r)分别为,PLT-I 0.991、0.997、0.997,PLT-O0.997、0.998、0.992;在RBC碎片干扰试验中,PLT-O对低值样本显示出较强的抗干扰能力(t=1.14,P>0.05),PLT-I与PLT-O测定血小板结果与PLT-M结果相关性良好。结论 Sysmex XE-5000对血小板计数具有精密度好、抗干扰能力强、重复性好、检测速度快等优点,是常规实验室测定血小板的较理想仪器。
