A method for the screening of human sera for tetanus antibodies has been developed and evaluated. The toxin binding inhibition test (ToBI-test) is based on inhibition of the binding of tetanus toxin to an antitoxin-coated immunoassay microtitre plate by tetanus antibodies. Serum samples from 191 healthy adults with different vaccination histories have been titrated for tetanus antibodies by the toxin neutralization (TN) test in mice, by toxoid-ELISA and by the ToBI-test. In every respect, the ToBI-test proved to be the best in vitro alternative to the TN-test in mice. Comparison showed a higher degree of correlation between the ToBI-test and the TN-test than between the toxoid-ELISA and the TN-test. Furthermore, no overestimation of antibody content was seen in titrating low titre by the ToBI-test. In contrast, several false positive results were seen when using the toxoid-ELISA. It is concluded that the ToBI-test is a reliable and precise alternative to the N-test and can be performed under simple laboratory conditions in a short time.
