Cut-off value of D-dimer in pulmonary thromboembolism and pneumonia
نویسندگان
چکیده
Aim: The differential diagnosis of pulmonary thromboembolism (PTE) and pneumonia remains difficult in emergency rooms. High D-dimer levels in the pneumonia may be misdiagnosed as PTE on the basis of similar clinical, radiological, and laboratory findings. Since D-dimer elevation may also be seen in pneumonia cases, the comparison of D-dimer values in patients diagnosed as pneumonia and PTE, in order to determine a cut-off value between the 2 diseases, was aimed in this study.

متن کاملDoes the Platelet Index Have a Guiding Role in the Association of Cancer and Pulmonary Thromboembolism?
Introduction: The diagnostic value of the D-dimer test varies with variable platelet numbers and functions in patients suffering from cancer and concomitant pulmonary thromboembolism (PTE). This requires easy and reliable evaluation tests. In this study, we aimed to investigate the hypothesis that platelet functions may be more guiding in the prediction and diagnosis of PTE rather than the numb...
متن کاملClinical usefulness of D-dimer testing in cancer patients with suspected pulmonary embolism.
Limited data are available about the diagnostic value of D-dimer testing in cancer patients with clinically suspected pulmonary embolism (PE). Therefore, we evaluated i) the safety and clinical usefulness of an ELISA D-dimer test to rule out PE in cancer patients compared with non-cancer patients and ii) whether adopting a higher D-dimer cut-off value might increase the usefulness of D-dimer in...

متن کاملAccuracy of D-dimer:fibrinogen ratio to diagnose pulmonary thromboembolism in patients admitted to intensive care units
INTRODUCTION Pulmonary thromboembolism (PTE) may increase D-dimer and decrease fibrinogen levels. However, in settings such as intensive care units (ICU) and in long-term hospitalised patients, several factors may influence D-dimer and fibrinogen concentrations and make them unreliable indicators for the diagnosis of PTE. The aim of this study was to evaluate the accuracy of D-dimer:fibrinogen ...
