126 patients with coagulation disorders were evaluated, hospitalized in the departments of the BacÄu County Emergency Hospital, between January and March 2021, aged between 18 and 96 years, who presented to the Emergency Reception Unit. Thus, an analysis of the changes in D-dimer values in the investigated patients was performed to establish the diagnosis of disseminated intravascular coagulation (CID), initiate therapy or continue it in patients already diagnosed. A small number of people (43) found a test value within the reference range (reference values, those considered to be a normal level of D-dimers, are set to be lower - <0.5 Îźg / mL FEU) , while 18 people had a value> 5 Îźg / mL FEU, which is higher than the linearity limit of the test.
