Medical terminology is a specialization of the medical informatics discipline. It is rare that organizations have personnel familiar with application of specialized medical termionlogies. With this in mind, VTSL provides educational services and opportunities for veterinarians.

Online resources: VTSL maintains a repository of presentations given by laboratory personnel that relate to veterinary implementation of terminology standards, including but not limited to SNOMED-CT. VTSL also maintains a public browser that has been developed and maintained to allow exploration of SNOMED-CT by interested parties.

Post-DVM Education: VTSL is a division of the Veterinary Medical Informatics program at the Virginia-Maryland Regional College of Veterinary Medicine. We offer formal training leading to either a masters of science or PhD in Veterinary Medical Sciences with an emphasis in veterinary medical informatics. Interested parties should contact the Biomedical and Veterinary Sciences program at the VMRCVM or visit their webpage.

Terminology Development

We believe that in order for SNOMED-CT® to contribute to Veterinary Medicine, its veterinary content must be enriched. VTSL acts, on behalf of various veterinary stakeholders, to facilitate the incorporation of high quality veterinary terminology content within the SNOMED-CT® universe.
