The discovery that D-dimer may be elevated in COVID-19 was first reported by physicians in Wuhan, China where the epidemic started.

D-dimer testing can combined with assessment of pretest probability be used to rule out VTE in patients with a sufficiently low pretest probability of VTE. Patients with a negative D-dimer result can be ruled out, while patients with a positive D-dimer result need to have imaging performed for confirmatory diagnosis. ...

The following is a copy of an article from Evidence-Based Practice, 2007; 10(12):1-2. Venous thromboembolism refers to a spectrum of disease that includes both pulmonary embolus and deep-venous thrombosis (DVT). More than 250,000 people in the United States are diagnosed annually with venous thromboembolic disease;...

CONTEXT: Sensitive D-dimer assays have been developed to exclude the diagnosis of deep vein thrombosis (DVT) and have exhibited great success when used in conjunction with a diagnostic algorithm, including pretest probability scoring and a compression ultrasound (CUS). Improving specificity of D-dimer assays would...

When a new D-dimer method is to be implemented either as a substitute for a currently used D-dimer assay or as a supplement, maybe as a point-of-care assay, it is necessary to do a clinical comparison of the "old" assay versus the "new" assay. The major pitfalls in D-dimer comparisons are addressed in this paper.   ...

Sepsis and septic shock lead to local and systemic activation of different response systems, including coagulation and fibrinolysis.  Despite numerous attempts the high mortality rate of these patients has remained stable over the last 20 years. In this overview the pathophysiological insights and possible...

Hemorrhage, due to a reduction in the coaguability of blood, is a common cause of morbidity and mortality among trauma victims and the critically ill in general. Reduced blood pH (acidosis) is also common in these patient groups. Previous studies have shown that acidosis is an independent risk factor for development...

Massive hemorrhage is a major cause of morbidity and mortality among critically ill patients. Conventional treatment is based on surgical control of bleeding and transfusion of blood products including red cells, platelets and fresh frozen plasma. Despite optimal conventional care, bleeding sometimes proves impossible ...
