The laboratory parameters, which include D-dimers, prothrombin time, platelet count and inflammatory biomarkers (including interleukin-6, C-reactive protein, ESR, procalcitoninin and ferritin), not only serve as markers of disease severity but can also guide decision making for early admission to the intensive care unit (ICU), intubation and ventilator therapy as well as the need for anticoagulation, in addition to assisting in determining the outcomes of COVID-19 patients [5]. The gene discussed is F2; the disease is COVID-19.
