D-Dimer test
D-D 雙合試驗
臨床意義
1.D-dimer為纖維蛋白分解產物(Fibrinogen degradation products)之一,當D-Dimer結果為陽性可用來診斷傳統 DIC (Disseminated intravascular coagulation)疾病;陰性時搭配臨床症狀可作為DVT (deep venous thrombosis) 及PE(pulmonary embolism)的排除診斷,結果為陽性時則需做進一步影像檢查確認是否為DVT及PE疾病。
2.下列狀況會造成偽性上升:溶栓治療、創傷、手術、血腫、惡性腫瘤、敗血症、嚴重感染、肺炎、肝硬化、懷孕、動脈粥樣硬化疾病、鐮刀性貧血、年紀超過60歲、長期臥床。
3.下列狀況會造成偽性下降:抗凝固劑治療、缺乏組織纖維溶酶活化劑、血栓凝塊太小、小孩子(研究指出小孩子患有PE與DVT者有15% 的機率D-dimer檢驗結果為正常)。
4.本檢驗方法敏感度:98.8%,特異性:34.2%,陰性預測率:98.7%
