Paucis Verbis: D-Dimer test

D-Dimer: To order or not to order?

That's the question when it comes to risk stratifying a patient for a pulmonary embolism with a low pretest probability. One should consider confounding conditions which may cause an elevated D-Dimer level. There's always confusion about what may cause an elevated D-Dimer besides venous thromboemboli. So I thought I would make a pocket card as a reminder.



Feel free to download this card and print on a 4'' x 6'' index card.
