Reagents and Proficiency Testing Available from the NVSL

Diagnostic reagents are produced by the National Veterinary Services Laboratories (NVSL) as needed for veterinary diagnostic use when a commercial source of reagent is not available or when commercial sources are not fulfilling diagnostic needs. Proficiency testing is offered for diagnostics associated with USDA program diseases, as well as other diseases requiring APHIS laboratory approval, and quality control purposes.

Items requested from the National Veterinary Services Laboratories catalog may not be available or may be limited in quantity at any time due to domestic testing or production priorities.
