D DIMER TEST

A D-dimer test is a blood test that measures D-dimer, which is a protein fragment that your body makes when a blood clot dissolves in your body. D-dimer is normally undetectable or only detectable at a very low level unless your body is forming and breaking down significant blood clots. A D-dimer test is a simple blood test that can help your healthcare provider determine if you may have a blood clotting condition.
