SuPAR in Adult Patients With Covid-19

Participants will undergo sampling of peripheral venous blood, immediately after admission. Blood samples drawn from all patients and EDTA plasma will be stored at -80° C until later measurement. Plasma suPAR levels will be determined using the suPARnostic® ELISA assay (ViroGates, Denmark), which is based on a simplified double monoclonal antibody sandwich ELISA assay whereby samples and peroxidase-conjugated anti-suPAR are first mixed together and then incubated in anti-suPAR pre-coated micro wells. The recombinant suPAR standards of the kit are calibrated against healthy human blood donor samples. suPAR concentrations are determined as ng/mL plasma.
