A Step Toward a Full-Service Diagnostic Facility
Solo Select Diagnostics is led by Dr. Kianna Spencer, DVM, MS, DACT, alongside Victoria Goodson, both of whom have completed official training and proficiency testing through the National Veterinary Services Laboratory (NVSL).The lab’s USDA approval enables Solo Select to process official Coggins tests, a critical service for horse owners requiring proof of EIA-free status for travel, sales, and competition. This includes the rapid 1-hour rapid Coggins tests.
Beyond Coggins testing, Solo Select Diagnostics is building a comprehensive diagnostic lab that will eventually provide a range of veterinary tests to support breeding, performance, and general equine health management.
"This is just the beginning," said Smith. "Our vision is to continue growing this facility and, in the future, likely open it to the public, ensuring more horse owners and breeders have access to quick and accurate diagnostics."
Expanding Diagnostic Capabilities
with Cutting-Edge Technology
Solo Select Diagnostics continues to push the boundaries of on-site equine healthcare with advanced testing capabilities. The addition of the Fluxergy machine allows for rapid PCR testing for strangles and salmonella, reinforcing Solo Select's commitment to disease surveillance and prevention.
"Maintaining the highest standard of equine health is our priority," said Dr. Kianna Spencer, DVM, MS, DACT. "Our advanced testing capabilities allow us to proactively monitor our facilities and ensure they remain disease-free, providing a safe and biosecure environment for every horse in our program."
Additionally, Solo Select Diagnostics now offers in-house endometrial cytologies alongside uterine cultures, elevating the quality and speed of reproductive diagnostics.
