妊娠期女性机体会产生一定的生理变化，血液处于高凝状态，同时启动代偿性纤溶系统，有助于产后快速止血、清除静脉血栓。但D-二聚体异常升高则会导致不良妊娠结局，严重者则会威胁到母婴生命。因此，D-二聚体作为血栓形成的一项无创性、无放射性损伤的指标，动态监测其变化，制定合适的妊娠期参考范围，对临床诊断，及时治疗具有指导性作用。

During pregnancy, the female body will produce certain physiological changes, the blood is in the state of hypercoagulation, and the compensatory fibrinolysis system will be started at the same time, which is helpful for postpartum rapid hemostasis and clearing of venous thrombosis. However, the abnormal increase of D-dimer will lead to the adverse pregnancy outcome, and the serious cases will threaten the lives of mothers and infants. Therefore, as a noninvasive and radiation-free index of thrombosis, D-dimer can dynamically monitor its changes and establish a suitable reference range for pregnancy, which has a guiding role in clinical diagnosis and timely treatment.<br>
