The literature suggests that this marker offers a higher accuracy than that offered by CRP and PCT in identifying the severity of the disease and the response to treatment, thus allowing identification of the multiple complications related to endothelialitis induced by SARS-CoV-2 virus including thromboembolism and acute respiratory distress [17,18,19,20,21,22,23,24]. This evidence concerns the gene CRP and Thromboembolism.
