Blood viscosity of COVID-19 patient: a preliminary report.

Abstract

COVID-19 is the important global problem. This new coronavirus can cause several hematological changes. Thrombosis is a problem might occur in COVID-19. In COVID-19, thrombosis might be the result of endothelial dysfunction, platelet activation, increasd blood viscosity, and blood flow disturbance. The change of blood viscosity in the patients with COVID-19 is possible but little mentioned. Here, the authors report on a preliminary data on blood viscosity assessment among 41 COVID-19 patients. According to the estimation, the estimated blood viscosity values are 72.4 ± 18.6 and 18.2 ± 2.2 for high and low shear rates. Based on this preliminary report, the increased blood viscosity is detected in COVID-19 patient and it might be associated with thrombohemostatic problem.
