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 result of the test is less than 300 ng/mL.
11/19/2015 · The study developed the age-adjusted D-dimer with a receiver operating characteristics (ROC) curve. 14 In JAMA 2014, Righini et al. published a prospective study utilizing the age-adjusted cutoff. AGE ADJUSTED D-DIMER CUTOFF = (AGE X 10) ?g/L **Applies to 50+ years old. THE PROSPECTIVE STUDY: Age-Adjusted D-dimer Cutoff.

8/3/2019 · Assessment of the safety and efficiency of using an age – adjusted d – dimer threshold to exclude suspected pulmonary embolism. Chest. 2014 May 15. doi: 10.1378/chest.13-2386. PMID : 24831769. Authors Conclusion: Use of an age – adjusted d – dimer threshold reduces imaging among patients age <50 years with a Revised Geneva Score ? 10.If reported by the lab as a D - dimer unit (DDU) the cutoff is often 230 ng/mL. 2 FEUs equal 1 DDU. Age (years) x 10 ug/L for patients > 50 years of age Patient age 75 = age adjusted d-dimer of 750 ug/L If using a lab with a cutoff of 230 (DDU assay) then formula is Age x 5
