[53] [54] Levels of antibodies are analysed by performing dilutions on blood serum. An ANA test is considered positive if fluorescence is seen at a titre of 1:40/1:80.

This registry based, multi-center, multi-country data provide provisional support for the use of ECMO for COVID-19 associated acute hypoxemic respiratory failure. Given that this is a complex technology that can be resource intense, guidelines exist for the use of ECMO during the COVID-19 pandemic. [85] [86] [87]
