Welcome to the Utah Veterinary Diagnostic Laboratory

The UVDL is open and fully operational during the COVID-19 outbreak

The Utah Veterinary Diagnostic Laboratory (UVDL) is a cooperative effort by Utah State University (USU) and Utah Department of Agriculture and Food (UDAF). The purpose of the laboratory is to provide timely, in-depth, cost efficient, veterinary diagnostic services to safeguard animal health, protect the agricultural economy, and shield the public against zoonoses (diseases transmissible from animals to humans). In these roles, the UVDL serves practicing veterinarians, personnel in regulatory state and federal governmental positions, public health officials and animal owners. Diagnostic services include pathology, bacteriology, virology, serology, toxicology and molecular-based assays. The main laboratory is on the campus of USU in Logan, Utah, and a branch laboratory is in Spanish Fork, Utah; together these laboratories constitute the Utah component of the national veterinary diagnostic laboratory system.
