深静脉血栓形成（DVT）的明确诊断有赖于影像学检查，但影像学检查对疾病确诊存在滞后性。试验指标在早期发现、协助诊断DVT具有非常重要的价值。临床上诊断DVT的试验指标种类繁多，标准不一，笔者结合文献对部分试验指标如：D-二聚体、纤维蛋白原、C-反应蛋白、超敏C-反应蛋白、血管内皮生长因子、Slit2蛋白等的研究进行综述，旨在寻找特异性及敏感性均较高的试验指标，为DVT的临床诊治决策提供有价值的证据。“,”Diagnosis of deep vein thrombosis (DVT) depends on imaging examination, but imaging examination has a time lag for disease diagnosis. Laboratory test indexes have important value in early detection and helping in the diagnosis of DVT. Since there are a wide variety of test indexes for DVT with different standards in clinical practice, the authors in this article, based on literature review, address some test indexes that include D-dimer, ifbrinogen, C-reactive protein, high-sensitivity C-reactive protein, VEGF and Slit2 protein, intending to look for highly sensitive and speciifc test indexes for providing valuable information to assist clinical decision making in diagnosis and treatment of DVT.
