With these measurements we measure the D-dimer in the blood. D-dimers are breakdown products of clots (or more precisely, of fibrin networks). So a clot, such as a deep vein thrombosis (DVT) and its breakdown, the D-dimers are increased.
What can you do with the D-dimer test?
With the D-dimer test you can detect the presence of blood clots. Blood clots can occur in various conditions such as deep vein thrombosis (DVT). This is a clot in a leg vein. It is possible that a a clot from the leg moves to the lungs. This is called a pulmonary embolism. This can be life-threatening. Another condition is diffuse intravascular coagulation (DIC), in which clots and hemorrhages regularly occur throughout the body. However, there are more conditions and abnormalities that can cause an increased D-dimer.
What does a negative result mean?
If the D-dimer result is negative, it is very unlikely that the complaints are caused by a blood clot in the bloodstream. It is a quick and low-stress test to rule out abnormal or excessive clotting. The D-dimer test is usually performed in combination with other tests to increase the certainty of the diagnosis.
