D-dimer is a blood test performed in the medical laboratory to diagnose thrombosis. Since its introduction in the 1990s, it has become an important test performed in patients suspected of thrombotic disorders. While a negative result practically rules out thrombosis, a positive result can indicate thrombosis but also has other potential causes. Its main use, therefore, is to exclude thromboembolic disease where the probability is low.

Thrombophilia is the potential to develop dangerous blood clotting in the veins or arteries. Several types of conditions have been identified which may lead to dangerous clots. These conditions may be present at birth (congenital or inherited) or may occur as a result of another condition (acquired).

An abnormal blood clot inside a blood vessel is called thrombosis. Thrombosis has been described as coagulation occurring in the wrong place or at the wrong time. The end result of thrombosis is an obstruction of the blood flow. Since the leading cause of death in the Western world is the formation of an abnormal blood clot inside a blood vessel, it is important for healthy people to take steps to prevent thrombosis. For those with risk factors for developing thrombosis, aggressive actions must be taken to protect against stroke, heart attack, kidney failure, pulmonary embolus, etc. As noted above, thrombi are clots that form in a blood vessel or in the wrong place: in an artery, a vein, or in

When you cut or injure yourself, your body stops the bleeding by forming a blood clot. Proteins and particles in your blood, called platelets, stick together to form the blood clot. The process of forming a clot is called coagulation. Normal coagulation is important during an injury, as it helps stop a cut from bleeding and starts the healing process. However, the blood shouldn't clot when it's just moving through the body. If blood tends to clot too much, it is called hypercoagulation or a hypercoagulable state (also called thromboembolic state or thrombophilia).
