About Age-Adjusted D-dimer Cutoff

This tool aids clinicians in evaluating D-dimer probability for patients over 50 years old, enhancing diagnostic accuracy for venous thromboembolism (VTE). Traditional D-dimer cutoffs often lead to increased false positives in older individuals due to age-related D-dimer elevation. By applying an age-adjusted threshold—typically calculated as age multiplied by 10 ng/mL for those above 50—this tool helps differentiate true VTE risk from physiological age-related increases. It supports more precise risk stratification, potentially reducing unnecessary imaging and anticoagulant use. This approach optimizes patient management and healthcare resource utilization by providing a more nuanced and accurate assessment in an age group prone to elevated D-dimer levels.
