Although D-dimer results within a typical range can rule out pulmonary embolism, high results alone can’t diagnose this condition. Doctors usually need to run extra tests to make a diagnosis.

Plasma d-dimer levels to rule out pulmonary embolism in hospitalized COVID-19 patients is not the right assay to use, new research suggests. Most patients already have levels greater than 0.05 μg/mL.

Level 1: Likely reliable evidence D-dimer plus multidetector CT (D-dimer/CT) is as effective as D-dimer/CT plus venous compression ultrasound (US) for identifying pulmonary embolism (PE) and short ...

A negative D-dimer test (one that rules out pulmonary embolism) can help patients avoid more expensive, invasive diagnostic tests, like a computed tomography pulmonary angiogram, or CTPA.

Patients who have suffered from a first episode of unprovoked venous thromboembolism (VTE) have an eight times higher risk of recurrence if they stop treatment after repeated negative D-dimer ...
