Determination of the quantitative D - dimer in blood plasma on the analyzer

D-dimer is a marker of the active thrombosis process.

The process of thrombosis involves the activation of fibrin fibers, which "braid" the thrombus and make it more durable. After a thrombus has formed, the body begins to dissolve it – this is called fibrinolysis. As a result of fibrinolysis, its fragment, the D–dimer, is detached from the fibrin fiber. Consequently, a high concentration of D-dimer in the blood indicates a pronounced process of fibrinolysis, which can only occur in the presence of a large thrombus in the body.

Thus, the main purpose of the test is to confirm or exclude thrombosis of any localization (lungs, veins of the lower extremities, etc.). The test is very important for practitioners, as it allows them to identify life-threatening conditions and start appropriate treatment on time.

The following factors affect the level of D-dimer in the blood: the size of a thrombus, taking antithrombotic drugs (anticoagulants).
