  • D-Dimer Test: MedlinePlus Medical Test

    2021-6-10 · A D-dimer test looks for D-dimer in blood. D-dimer is a protein fragment (small piece) that's made when a blood clot dissolves in your body. Blood clotting is an important process that prevents you from losing too much blood when you are injured. Normally, your body will dissolve the clot once your injury has healed.

  • D Dimer Blood Test - Accuracy, Purpose, Procedure,

    2018-5-25 · D-dimer is one of the protein fragments produced when a blood clot gets dissolved in the body. It is normally undetectable or detectable at a very low level unless the body is forming and breaking down blood clots. Then, its level in the blood can significantly rise. This test detects D-dimer in the blood.

    Production of D-dimer from fresh clots falls of after about 2 weeks so the duration of the thrombi is also a consideration. Whether superficial phlebitis will elevate the dimer is a function of the amount of fresh clot there is to lyse, thus I expect the dimer response would be variable. Thanks, John.
