Any equidae which are positive to an official EIA test are to be declared infected with EIA and designated as an EIA reactor. The Administrator may require or recommend a re-test of EIA reactors in order to confirm infection or identification of the animal. In cases where a confirmatory test is conducted, the final determination of infection will be delayed until the results of the confirmatory test are available. The animal on which a confirmatory test is to be conducted will be placed under an official Hold Order until the results of the confirmatory test are available.
