The immunogram (quantitative TBNK immunophenotipisation) will be performed by flow cytometry, the antibody response will be determined by IVD ELISa.
Clinical biochemical and immunochemical (ECLIA) tests (including IL-6) will be performed on Cobas analyzers. Hemogram with differential blood picture will be performed with a hematology analyzer Sysmex XN 3100, examination of blood smears with CellaVision system or. microscope. Coagulation tests will be performed on BCS XP analyzers.
An in-house system for the analysis of SARS-CoV-2 virus fusion inhibitors on human cells will be used to detect the ability of antibodies from patients' serum to neutralize the virus and thus potential protection against re-infection. The system is quantitative, meaning that the titer of such antibodies could be determined, and thus the potential level of protection would be evaluated.
