FYI all members,
D-dimer tests are ordered, along with other laboratory tests and imaging scans, to help rule out, diagnose, and monitor diseases and conditions that cause a tendency to clot inappropriately.
D-dimer may be ordered when a patient has symptoms of DVT, such as leg pain, tenderness, swelling, discoloration, edema; or symptoms of PE, such as labored breathing, coughing, and lung-related chest pain. D-dimer is especially useful when the doctor thinks that something other than DVT or PE is causing the symptoms. It is a quick, non-invasive way for the doctor to help rule out abnormal or excess clotting.
