UAC Pathology Services provides quality assurance testing and diagnostic and comparative pathology support for research animals and UAC centralized animal facilities at the University of Arizona. Quality assurance programs ensure that research animals do not harbor unwanted infectious diseases, environmental parameters are maintained within acceptable limits, and sanitization/sterilization procedures are effective. Diagnostic pathology support is routinely provided for any research animals that become moribund or die unexpectedly. Anatomic and clinical pathology support for research projects, including comprehensive and targeted pathologic phenotyping of genetically altered rodents, are provided on a fee for services basis. A wide range of animal, blood, and tissue analyses are available, with emphasis on laboratory rodent, rabbit, and primate species.
