This device is a diagnostic support utilized in healthcare settings to evaluate the chance of thromboembolic occasions, reminiscent of deep vein thrombosis (DVT) or pulmonary embolism (PE). It modifies the usual D-dimer threshold based mostly on a affected person’s age, sometimes by rising the cutoff worth. For instance, as a substitute of a common cutoff of 500 ng/mL, the brink is likely to be calculated as age multiplied by 10 ng/mL for people over 50 years outdated.
The applying of an age-adjusted method goals to enhance the specificity of D-dimer testing, lowering the variety of false-positive outcomes, significantly in older adults. Elevated D-dimer ranges can happen on account of varied non-thrombotic circumstances, that are extra prevalent with rising age. Using this adjustment can lower pointless imaging research, reminiscent of CT scans, resulting in lowered radiation publicity and healthcare prices. Traditionally, the adoption of adjusted thresholds represents an effort to refine diagnostic accuracy and optimize useful resource utilization within the analysis of suspected venous thromboembolism.
