Disseminated Intravascular Coagulation and Advances in D-Dimer Testing: Progress in Harmonization of Clinical Assays and Innovative Detection Methods.

The measurement of D-dimer, a fibrin degradation product, has become integral to diagnosing and managing thrombotic disorders, particularly disseminated intravascular coagulation. This report synthesizes current knowledge on D-dimer biochemistry, assay methodologies, clinical utility, and ongoing challenges in standardization. By analyzing recent advancements in harmonization efforts and innovative detection technologies, this review highlights the critical role of D-dimer in coagulation diagnostics while addressing persistent limitations in specificity and assay variability. Emerging techniques, such as mass-spectrometry and aptamer-based sensors, demonstrate promise for overcoming current barriers, though widespread clinical adoption requires further validation.
