Venous Thromboembolism (DVT/PE)
Which test(s) should I order for my patient with suspected PE?
Select the next diagnostic step based on pretest probability. Use Age-Adjusted D-dimer to improve specificity in older adults, YEARS to reduce unnecessary imaging (including during pregnancy), and 4PEPS for a comprehensive probability-based diagnostic strategy.
