Recently, a study showed that markers of neutrophil extracellular traps formation, a mechanism corresponding to neutrophil activation, were increased in patients who died of COVID 19 compared with survivors. The investigators propose to analyze the NEU-SFL parameter, obtained automatically on the Sysmex™ blood count machine (Sysmex Corporation, Kobe, Japan) and which is considered as a reflect of neutrophil extracellular traps formation, in these two groups of patients. The aim was to evaluate whether this parameter could be used to predict the risk of death related to COVID 19.
