Reagents and Proficiency Tests From 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.
ATTENTION
The Animal and Plant Health Inspection Service (APHIS) has announced its proposed adjusted user fee rates for the costs of providing certain veterinary diagnostic goods and services. View the Proposed fees on regulations.gov, APHIS-2023-0058. Note: NVSL staff cannot take feedback on the proposed fee changes. For ease of reference NVSL has created condensed catalogs to provide customers with the proposed fee changes.
