Elevated D-dimer levels are nonspecific and may indicate other conditions
Testing may be influenced by age, infection, and cancer status

Abstract

D-dimer testing is useful for excluding venous thromboembolism (VTE), where a low D-dimer level helps exclude deep vein thrombosis (DVT) and pulmonary embolism (PE).11 However, elevated levels are nonspecific and may occur with infection, cancer, pregnancy, and older age.11 For
