<prompt> D-dimer is the sensitive diagnostic test forPulmonary embolismAcute pulmonary oedemaCardiac tamponadeAcute myocardial infarction  <response>: The sensitivity of the d-dimer is 80 for DVT including isolated calf DVT and 95 for PE. The d-dimer is less sensitive for DVT than for PE because the DVT thrombus size is smaller.A normal d-dimer is a useful rule out test. However, the d-dimer assay is not specific. Levels increase in patients with myocardial infarction, pneumonia, sepsis, cancer, and the postoperative state and those in the second or third trimester of pregnancy.Ref: Harrisons 19e pg: 1632
