摘要:

目的 分析常规实验室标本-20 ℃冻融后对易栓症检测结果的影响。方法 收集西安交通大学第一附属医院80例枸橼酸钠抗凝血浆标本,测定其即刻(0 d)、-20 ℃保存3 d复融后即刻(3 d)和复融后4 ℃保存2 h(2 h)的抗凝血酶(AT)、蛋白C(PC)、狼疮抗凝物(LA)和蛋白S(PS)。比较不同时间点检测结果的差异。结果 AT、PC、LA在-20 ℃保存3 d且复融后2 h内结果稳定;PS结果则明显降低,但复融后4 ℃保存2 h内结果稳定。结论 枸橼酸钠抗凝血浆标本-20 ℃冻融对PS测定结果有一定影响,临床在诊断易栓症时应关注此种情况。

Abstract:

Objective To analyze the influence of routine laboratory specimens subjected to freezing and thawing at -20 ℃ on the determination results of thrombophilia. Methods A total of 80 sodium citrate anticoagulant plasma specimens from the First Affiliated Hospital of Xi'an Jiaotong University were collected. The levels of antithrombin(AT),protein C(PC),lupus anticoagulant(LA)and protein S(PS) were determined at the immediate time point(0 d),immediately after thawing at -20 ℃ for 3 d(3 d) and 2 h(2 h) after thawing at 4 ℃. The differences in determination results at different time points were compared. Results The levels of AT,PC and LA remained stable within 2 h after thawing at -20 ℃ for 3 d,while the level of PS was significantly decreased,but the results remained stable within 2 h after thawing. Conclusions Freezing and thawing of sodium citrate anticoagulated plasma at -20 ℃ has an impact on the determination results of PS. Clinicians should pay attention to this situation when diagnosing thrombophilia.
