How long must sera from positive EIA test samples be retained?

The retention period for sera from positive Equine Infectious Anemia (EIA) test samples is mandated by regulations to ensure adequate tracking and monitoring of this disease, which is transmitted by blood-feeding insects and can have severe consequences for equine health. Retaining these samples for a minimum of two years allows veterinary and regulatory authorities to effectively manage and contain potential outbreaks, perform epidemiological studies, and maintain comprehensive records for disease surveillance.

Keeping samples for two years also aligns with best practices in veterinary diagnostics and public health, as it provides sufficient time for contact tracing and investigation if another positive case emerges or if there's a need to revisit the results for any reason. This timeframe reflects the significant implications of EIA within equine populations and the importance of responsible disease management.
