Comparative study of the sensitivity of the serological methods used in detecting mumps virus antibodies

Six different methods were used for examinations for the presence of antibodies to mumps virus in 43 sera of donors varying in ages from 18 to 58 years. Judging by the percentage of positive results, most sensitive tests included: radial hemolysis (95.3), neutralization (88.4-81.4), immunofluorescence (83.7). Comparison of the results obtained in these tests revealed high correlation coefficients of antibody titres. The lowest number of positive results was obtained in lectin-neuraminidase test and hemagglutination-inhibition test (51.2% and 32.6%, respectively).
