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

During pregnancy, the female body will have certain physiological changes, the blood is in a hypercoagulable state, and the compensatory fibrinolysis system is activated at the same time, which helps to quickly stop bleeding and remove venous thrombosis after delivery. However, abnormally elevated D-dimer will lead to adverse pregnancy outcomes, and severe cases will threaten the lives of mothers and infants. Therefore, D-dimer as a non-invasive and non-radioactive indicator of thrombosis, dynamically monitor its changes, formulate an appropriate reference range during pregnancy, and have a guiding role in clinical diagnosis and timely treatment.

During pregnancy, the female body will produce certain physiological changes, blood in a high coagulation state, while the initiation of the compensation of the fibrous system, help to quickly stop the bleeding after the post-partum, remove venous thrombosis. However, abnormally elevated D-dipolymer can lead to adverse pregnancy outcomes, which can threaten the lives of mothers and children. Therefore, D-dipolymer as a non-invasive, non-radioactive damage index of thrombosis, dynamic monitoring its changes, the development of a suitable reference range for pregnancy, clinical diagnosis, timely treatment has a guiding role.

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.
