Abstract
目的制备BCR-ABL (P210)实时定量PCR(RQ-PCR)检测的室内质控物,建立RQ-PCR检测BCR-ABL (P210)转录本水平的室内质控方法。方法取K562细胞和HL-60细胞,制备RQ-PCR检测BCR-ABL(P210)转录本水平的高、低浓度质控物,2013年8月至2015年10月用RQ-PCR法与临床标本同步检测BCR-ABL(P210)184次,按试剂批号(批号20130303、20131212、20140411和20150327分别简称为R1、R2、R3、R4)统计分析标准曲线斜率、截距及相关系数,并按试剂批号和质控物批号(批号20130725、20140611分别简称为Q1、Q2)统计分析高、低浓度质控物检测结果,对斜率、截距及质控物检测结果采取Levey-Jennings质控图结合Westgard多规则质控方法进行质控判断。结果①标准曲线斜率、截距:R1检测53次,斜率、截距均未失控;R2检测37次,斜率失控6次,且第2~8次在x−s限值下侧,第12~37次在x值上侧,截距失控9次,且第1~8次在x+s限值上侧,第12~37次出现在x值下侧;R3检测80次和R4检测14次,斜率、截距均未失控。②质控物结果:Q1批号质控物,R1检测49次未失控,R2检测23次失控1次;Q2批号质控物,R2检测14次、R3检测72次及R4检测14次均未失控。结论利用K562细胞和HL-60细胞制备定量检测BCR-ABL(P210)转录本水平的高、低浓度室内质控物,制备方便,检测结果可靠、稳定,使用质控物检测结果结合标准曲线斜率、截距进行室内质控,可更有效地保证临床检测结果的准确性和稳定性。
