A normal D-dimer essentially excludes DIC. Advanced sepsis-induced DIC may impair fibrinolysis (“fibrinolytic shutdown”), which limits further increases in D-dimer. thrombocytopenia. Moderate thrombocytopenia is usually seen in DIC.

Webb8 juli 2024 · CT pulmonary angiography (CTPA) is the preferred imaging modality to detect pulmonary embolism (PE) but whether D-dimer levels can guide selection for CTPA is uncertain. Emerging evidence has indicated a high incidence of thromboembolic events, including pulmonary embolism (PE) in patients with COVID-19. WebbD-dimers in patients with low or moderate Wells score were analysed for both conventional and age-adjusted cut-offs. The use of an adjusted D-dimer showed a sensitivity of 0.97 (95% CI 0.9–1.0) while the specificity increased from 0.07 (95% CI 0.04–0.11) for the conventional cut-off to 0.32 (95% CI 0.27–0.38) for the age-adjusted cut-off. 9局職業棒球2022破解版
