What other procedures may my doctor order if my D-dimer is positive?
In an emergency room setting, if you are found to be at low-to-intermediate risk for thrombosis and/or venous thromboembolism and when you have a positive D-dimer test, your doctor will likely order a non-invasive scanning procedure, such as a venous ultrasound or CT angiography. Additional procedures may include ventilation/perfusion scan or pulmonary angiography. For more on these, see Radiologyinfo.org: Heart and Vascular.
