A member asked:
Why do anticoagulants sometimes cause a false negative d dimer? if the thin the blood and don't affect fdp i don't see why they would cause an effect?

Different : FSP and D Dimer are not synonymous.. D dimer is a by-product of clots and when the anticoagulants prevent formation or clots, d-dimer will be low or falsely negative. D-dimer off anticoagulation can rough predict the risk of recurrent clots.
