Newcastle disease or pseudo-plague is a highly contagious viral bird disease, characterized by damage to the respiratory and digestive organs, as well as impaired central nervous system function. Since the middle of the last century, this disease has become widespread in many European countries. Newcastle disease is common in all continents and is especially dangerous. The article provides information on conducting a round of commission tests of the components of the test system “A Kit for Detection of Antibodies to Newcastle Disease Virus in Hemagglutination Inhibition Test”. When testing encrypted antigens and sera with previously characterized and referent samples, they were active and specific, meeting the requirements of the technical specifications of Ukraine for the specified drug. Thus, the positive antigen had activity in the hemagglutination test of 1:256, reacted only with positive to the Newcastle disease virus serum, and did not delay agglutination in the presence of referent to avian influenza virus subtypes H5 and H7 sera. In the presence of positive sera to the Newcastle disease virus in encrypted form, the positive antigen of the corresponding virus delayed the agglutination of the cock erythrocytes in dilutions 1:256–1:512. The results obtained allowed to make a positive decision on the registration of this preparation in the territory of Ukraine
