Discourse communities require a network of communication where the members of it can be any amount of distance apart as long as they operate with the same language, but speech communities require proximity to convey the culture of their language.
Pragmatic classification of the causes of high D-dimer. Abstract. Venous thromboembolism (VTE) remains the most. common preventable cause of in-hospital death and D-dimer. (DD) is one of the essential diagnostic tools for it. Each risk. factor for VTE can raise DD and they are numerous: 24 listed in 2008 European Guidelines.
Since D-dimer is a sensitive test but has a poor specificity, it should only be used to rule out deep vein thrombosis (DVT), not to confirm a diagnosis. It should not be used for pulmonary embolism when the clinical probability of that condition is high.his test may be used to determine if further testing is necessary to help diagnose diseases and conditions that cause hypercoagulability, a tendency to clot inappropriately. A D-dimer level may be used to help diagnose disseminated intravascular coagulation (DIC) and to monitor the effectiveness of DIC treatment.
