OBJECTIVE From the beginning of the novel coronavirus infection (COVID-19) pandemic in the world, much efforts have been accomplished to explain a precise clinical feature for the disease and to find the best therapeutic approach for the patients. Although coagulation abnormalities have found in novel coronavirus infection (COVID-19) patients, still little is known about the association between the disease and changes in coagulation parameters. Our purpose is to evaluate the differences between the coagulation parameters between COVID-19 patients and healthy counterparts. PATIENTS AND METHODS 63 patients with confirmed COVID-19 infection were admitted to the present study. We evaluated coagulation value in these patients and in 40 healthy individuals. RESULTS We found that although there was no significant difference between PT and PTT values in patients and healthy counterparts, the fibrinogen values in patients were higher than the control group (p < 0.05). Moreover, the values of fibrin/fibrinogen degradation products (FDP) and D-dimer in all COVID-19 cases were considerably higher than those in control people (p < 0.05). Of note, FDP and D-dimer in patients with regular COVID-19 infection were lower than patients with severe forms. CONCLUSIONS It seems that the conduction of routine blood coagulation test could be a beneficial supplementary approach for early diagnosis of COVID-19. In addition, our study shed more light on the therapeutic value of anti-coagulant-based treatment for COVID-19 patients, especially for those with severe type of the disease.
