Test BackgroundD-dimer results are often used in conjunction with the Well’s score (an index of clinical suspicion of venous thromboembolism) in determining the diagnostic probability of a VTE. A negative d-dimer result is indicative of a low probability of VTE, but a raised d-dimer result may be due to many other factors, eg. infection, inflammation and pregnancy, and so should not be used to confirm a VTE diagnosis in the absence of any other supporting evidence.
