COVID-19-related coagulopathy can present different coagulation changes with different stages of the patients.[9] Complex mechanisms such as cytokine storm, sepsis/severe infection, and organ injury may all be involved in these coagulation disorders.[9] An early coagulation activation stage was characterized by elevated D-dimer levels, fibrinogen, PT, and so on. The gene discussed is F2; the disease is blood coagulation disease.
