The Animal Health Diagnostic Laboratories are operated under the direction of the state veterinarian. The laboratories were established to help the division identify, control and eradicate those livestock diseases that threaten the profitability and marketability of Missouri’s livestock and livestock products. Laboratory services are free for those tests required by a state/federal cooperative eradication program. In Missouri, the two diseases covered by a cooperative program are pseudorabies and brucellosis (except B. canis). In January 1994 the division was granted the authority to charge fees for a variety of other diagnostic services. The fees were established to help offset the cost of maintaining the laboratories and to upgrade equipment so that new and advanced tests can be run.
