Question

A 61-year-old with low-intermediate pretest probability of PE (Wells 2.0) is 72 years old. D-dimer (FEU) is 620 ng/mL. Which statement is correct?

Accepted Answer

Age-adjusted D-dimer threshold is 72 x 10 = 720 ng/mL FEU; PE cannot be excluded

Answer

Age-adjusted D-dimer threshold is fixed at 500 ng/mL FEU after age 50

Answer

PERC should be used; D-dimer is unnecessary at any non-high probability

Answer

D-dimer must be

Answer

Imaging is mandatory regardless of D-dimer in low-risk patients
