【摘要】Objective: coagulation four and D - dimer measurement has been changed to the same blood tube instrument measuring, in order to define the measurement in the process of influencing factors, reasonable arrangement of col ection time, study the specimen placed on blood coagulation time four and D - dimer determination results, the influence of codes for analysis of the process to provide experimental basis. Methods: randomly selected 30 determination of sodium citrate anticoagulation peripheral blood specimens of blood coagulation four and the determination of D - dimer, room temperature placed 2h, 4h, 6 h after each measurement time, contrast analysis with instant results.%目的：凝血四项和D-二聚体测定已改为同一管血同一台仪器测定，为了明确测定过程中的影响因素，合理安排采血时间，研究标本放置时间对凝血四项和D-二聚体测定结果的影响，为规范分析前过程提供实验依据。方法：随机选取30份枸橼酸钠抗凝的外周血标本测定凝血四项和D-二聚体测定，室温放置2h，4h，6h后各测定一次，与即时结果进行对比分析。结果：即时结果与室温放置2h .4h测定结果比较，凝血酶时间和活化部分凝血酶时间测定结果差异有统计学意义（p<0.01）。D-二聚体即时结果与4h，6h测定结果差异有统计学意
