Web19 dec. 2024 · Elevated D-dimer levels may be seen in conditions in which fibrin is formed and then broken down, such as recent surgery, trauma, infection, heart attack, and some cancers or conditions in which fibrin is not cleared normally, such as liver disease. WebD-dimers are protein products of cross-linked fibrin degradation that are present in the blood of most healthy individuals in only negligible amounts (of the order 100-200 ng/mL). As objective evidence of increased fibrinolysis, elevated blood concentration of D-dimer is by extension evidence of intravascular coagulation and thrombotic disease.
