摘　　要：目的：探讨本院实际工作中血块形成对凝血三项及 D‐D 二聚体检测结果的影响，并对其原因进行分析。方法收集我院30例日常工作中发现有凝块的凝血标本，并要求临床立即重抽复检，比较重抽前后检测结果的差异。结果血凝的状态下，APTT 显著降低，DD 明显升高，而 PT 和纤维蛋白原（FIB）也相应降低，但不明显， P＜0．05，差异有统计学意义。结论血块形成对凝血项目检测结果影响较大，而且一些小凝块很容易漏检，检验人员可根据结果的异常来怀疑标本状态，进而仔细检查，以保证结果准确发出。Objective To investigate the Influence of blood clot formation on results of three tests for coagula‐tion and DD‐dimer in the practical work of our hospital ,and analyze the reasons .Methods Collect 30 cases found clot of blood coagulation specimens in the daily work in our hospital ,and calls for immediate clinical heavy smoke re‐check ,comparing the difference between the test results of before and after the heavy smoke .Results When the Blood clot ,APTT significantly reduced ,DD increased significantly ,PT and fibrinogen （FIB） also corresponding re‐duced but not significantly ,P〈 0 .05 ,the difference was statistically significant .Conclusion Blood clot formation had a greater influence on the test results of coagulation ,and a few small clot is easy to leak .Inspectors can doubt the state of specimens according to the abnormal results and then carefully check them to ensure that the results are accu‐rate .
