摘要
目的对Sysmex CA-1500凝血仪D-二聚体进行性能评价,探讨D-二聚体在老年性腰椎退变性疾病患者术后诱发深静脉血栓(DVT)形成的临床诊断价值。方法参考CLSI EP5-A2方案对D-二聚体性能进行评价。收集临床诊断为老年腰椎退变性疾病患者37例,对患者术前及术后不同时间点血清中D-二聚体进行定量检测。结果 D-二聚体的准确度、不精密度、线性范围、携带污染率、临床可报告范围均符合厂家要求。在37例患者中术后即刻与术后2周D-二聚检测值较高,处于临床血栓高风险状态;围术期内不同时间D-二聚体检测与术前相比有明显差异,具有统计学意义(P<0.01)。结论老年性腰椎退变性疾病以D-二聚体作为术后下肢深静脉血栓形成的预测和诊断手段,其灵敏性、特异性以及准确性均相对较高。
Objective To evaluate the performance of D-dimer of Sysmex CA-1500 coagulometer,and to evaluate the clinical value of D-dimer in the diagnosis of deep vein thrombosis( DVT) after lumbar degenerative disease. Methods The performance of D-dimer was evaluated by referring to CLSI EP5-A2. A total of 37 patients with senile degenerative lumbar degenerative diseases were collected,and serum D-dimer was quantitatively measured at different time points before and after operation. Results D-dimer accuracy,imprecision,linear range,carrying pollution,clinical reportable range were in line with manufacturers requirements. D-dimer detection was higher in 37 patients and at 2 weeks' post-operatively,which was at high risk of clinical thrombosis. D-dimer detection was significantly different at different time points before and after operation,with the differences statistically significant( P 0. 01). Conclusion D-dimer is the predictive and diagnostic method of deep venous thrombosis of the lower extremity after senile degenerative lumbar degeneration. The sensitivity,specificity and accuracy of the method are relatively high.
