Indirect fluorescent antibody (fa) and agar gel precipitin (agp) tests were used to detect antibody in serums of chickens which were exposed to Marek's disease (md) virus. There was a 92% agreement between the results of the fa and those of the agp tests on 418 serums from various sources. By the fa test, maternal antibody in young chickens from md-exposed dams was detected after antibody was no longer detectable by the agp test, and acquired antibody in contact-exposed chickens was detected earlier than by the agp test. The fa test was 10 to more than 320 times more sensitive than the agp test; also, some serums which had a high titer of antibody demonstrable by the fa test did not produce precipitation in the agp test.
