摘要 目的初步探讨不同血凝仪检测活化部分凝血活酶时间(APTT)结果的一致性。方法按照EP-2A方案,以ACL-Ad-vance仪及配套ACL试剂检测40例枸橼酸钠抗凝标本APTT结果为Y,CA-7000仪及CA试剂检测APTT结果为X1,CA-7000仪及ACL试剂检测APTT结果为X2,分别进行相关性分析,并判断两个医学决定水平(25 s、50 s)处的临床可接受性。用ACL-Advance仪(ACL试剂)和CA-7000仪(ACL试剂)检测80例不同肝素浓度标本及20例用肝素抗凝治疗患者标本的APTT,并比较差异是否有统计学意义。结果 Y=0.843 5X1-0.318 5,r2=0.928 0;Y=0.984 6X2+0.333 9,r2=0.989 5;各仪器均使用ACL试剂时APTT结果临床均可接受。两台仪器统一使用ACL试剂检测不同肝素浓度标本及临床肝素抗凝治疗患者标本APTT,结果差异均无统计学意义(P>0.05)。结论同一科室不同血凝仪应使用相同APTT试剂,以保证结果的一致性和可比性。
