Review of Clinical Utility of Age-Adjusted D-Dimer Assay

WebA value of D-dimer above 500 FEU (0.5µg/mL) was considered the cutoff value above which imaging modality was mandated. Age-adjusted D-Dimer threshold was calculated by multiplying the age of the patient 50 years and above by 10 [Age-adjusted D-dimer (FEU) =Patient’s age x10) or [Age-adjusted D-dimer (µg/mL) = (Patient’s age x10)/1000]. WebBut this represents the vast majority of tests used. Limited data exist on D-dimers with cutoffs set at 250 ng/mL. Retrospective studies suggest that in this case, the age-adjusted cutoff is “age per 5”, meaning that you can rule out PE in a patient of 60 years if the …
