Blood viscosity predicts mortality in severe COVID-19: study

US data point to potential role of haemodynamic measures in predicting in-hospital death

Elevated whole blood viscosity in patients hospitalised with COVID-19 is associated with a more than 50% increased risk of death, results from the first large-scale study of its kind show.

According to US researchers, estimated high-shear blood viscosity — calculated via routine lab tests — could be used as a risk assessment tool to offer preventive therapy in this setting.
