Summary
We report a comparison of radioimmunoassay with conventional serology in the detection of brucella abortus antibody from three laboratories. Overall agreement by Chi squared analysis is 5%. There are significant differences between laboratories and a significant number of sero negative suspect sera (from 20% – 60%) were positive by radio-immunoassay test. We suspect that conventional serology under-reports the incidence of antibody to brucella abortus.
