Use of serologic testing to assess immune status of companion animals.

At the November 1997 meeting of the AVMA Council on Biologic and Therapeutic Agents, the Council recommended that the JAVMA publish an article on the current status of the use of serologic testing in an effort to assist practitioners who must make decisions regarding vaccination of companion animals (i.e., dogs, cats, and horses). It is anticipated that the peer-reviewed article provided here will be of benefit to veterinarians and will facilitate their attempts to maintain animal health through the knowledgeable use of vaccines.
