FIELD: medicine.
SUBSTANCE: group of inventions relates to the field of medicine, including veterinary medicine, in particular to the serological diagnosis of infectious diseases common to humans and animals (COVID 19 is also of them). The essence of the group of inventions consists in using a diagnostic kit that includes all the necessary components for enzyme immunoassay, which provides detecting the SARS-CoV-2 virus in blood serum samples at an early stage of the disease with high specificity and sensitivity due to a fragment of the N SARS CoV 2 protein immobilized on the surface of microplate wells coated with albumin by silver nanoparticles. The group of inventions also relates to a method for detecting infection of humans and animals with SARS CoV2, implying the study of human and animal blood serums for the presence of antibodies to SARS CoV2 antigens immobilized on the surface of the EIA microplate, in the absence of antibodies to SARS CoV2, a person is considered to be in contact with this virus, in the case of detection of antibodies in an animal (cat) contacting only with its owner.
EFFECT: group of inventions provides sensitive and effective serological diagnostics of COVID-19 at the early stages of the disease development.
