The present investigation relates the results obtained by the indirect immunobead test (IBT) to those found during the tray-agglutination test (TAT) and sperm immobilization test (SIT) performed on 16 positive blood sera samples. An IB binding of greater than 50% can be regarded as significantly positive (p less than 0.05), since 77% of the positive IB samples with an IB binding of greater than 50% also revealed a TAT titer of greater than 1:8. The IBT is an excellent test for the detection of sperm antibodies during routine screening procedures.
