What is the D Dimer Test?
A D-dimer test checks for a small fragment of a protein, called D-dimer, that your body can make when you have an injury. Your body coagulation mechanism will dissolve the clot once your injury has healed in normal conditions. However, if you have a blood clotting disorder and there’s more than one clot being formed or trouble dissolving at once, in that case, the clots could block off other areas of your body’s circulatory system and cause serious symptoms. It can lead to internal bleeding and even death, so knowledge of d-dimer levels is important in detecting dangerous blood clotting disorders.
