Lupus anticoagulant testing, frequently the most sensitive marker in acute COVID-19 coagulopathy, was not performed, and we measured only IgG and IgM isotypes of anticardiolipin and anti-β2GPI antibodies, without evaluating IgA isotypes or anti-phosphatidylserine/prothrombin antibodies. This evidence concerns the gene CD79A and blood coagulation disease.
