D-dimer formation. Shown are fibrinogen, with its one E domain and two D domains, acted upon in cascade, by the following enzymes: Thrombin, to create a mesh of fibrin protofibrils; Factor XIII to crosslink the fibrin mesh (linking protofibril D domains), the scaffold for clot formation; Plasmin, whose action in fibrinolysis produces fibrin degradation products (FDPs), the smallest of which ...

In 2021, the items of the Revised Geneva Score were re-evaluated on pregnant women. [4] Some items were removed, and the threshold values for the remaining items were modified to better discriminate patients even with the altered physiologic baseline of pregnancy (e.g. higher cut-off value for heart rate, lower cut-off value for age).

In pregnancy, D-dimer is likely to be elevated and loses its use a diagnostic tool. No different normal range is used, because by increasing the cutoff you'd lose its sensitivity. In pregnancy clinical assessment and V/Q scanning is used. JFW | T@lk 19:06, 26 November 2006 (UTC)
Principles of D-dimer testing. Fibrin degradation products (FDPs), also known as fibrin split products, are components of the blood produced by clot degeneration. [1] Clotting, also called coagulation, at the wound site produces a mass of fibrin threads called a net that remains in place until the cut is healed. As a cut heals, the clotting ...
In people with a low or moderate suspicion of PE, a normal D-dimer level (shown in a blood test) is enough to exclude the possibility of thrombotic PE, with a three-month risk of thromboembolic events being 0.14%. [51] D-dimer is highly sensitive but not specific (specificity around 50%).
