Abstract

This study was conducted to assess the presence of an immune response in staff of DILA Medical Laboratory who have recovered from COVID-19, to study the features of monitoring indicators in different clinical variants of the disease. The obtained results allowed analyzing various types of the immune response in patients with a new coronavirus disease. In staff who has reco­vered from COVID-19, an immune response study was performed by determining the presence of immunoglobulins M and G to va­rious coronavirus target proteins by a semiquantitative method on a chemiluminescence immunoassay analyzer. The findings allowed us to assess not only the intensity of the immune response, but also the relationship with clinical manifestations, disease duration, age, which will be important for further comparative analysis with the immune response of vaccinated employees. The findings showed that most patients with COVID-19 produce protective antibo­dies, more often to the S-target, and also allowed determining the ave­rage duration of circulation of both immunoglobulin M and G antibodies.
