International standards for test methods and reference sera for diagnostic tests for antibody detection
1Canadian Food Inspection Agency, National Centre for Foreign Animal Disease, Manitoba, Canada.
Summary
International standards for diagnostic tests are crucial for animal trade. Establishing standard test methods and reference sera ensures reliable disease detection and global harmonization of animal health regulations.
Area of Science:
- Veterinary diagnostics
- International standards
- Animal health regulation
Background:
- Diagnostic tests are vital for animal movement between trading partners.
- Ensuring diagnostic test performance is essential for disease control and trade.
- Lack of standardized methods hinders international harmonization of animal health.
Purpose of the Study:
- To highlight the necessity of international standards for diagnostic tests.
- To explain the role of standard test methods and sera in ensuring diagnostic performance.
- To emphasize the importance of harmonization in animal health surveillance.
Main Methods:
- Establishing international standard test methods to set performance requirements.
- Developing international standard sera (positive and negative) for calibration.
- Using standard sera to calibrate the detection range and analytical sensitivity of tests.
Main Results:
- Standardized methods and sera provide a baseline for test performance evaluation.
- Calibration with standard sera improves the likelihood of tests achieving desired diagnostic sensitivity and specificity.
- Implementation of standards leads to a higher degree of international harmonization.
Conclusions:
- International standards for diagnostic tests and sera are indispensable for reliable animal health assessments.
- Standardization ensures that animals qualifying for movement are free from specific infectious agents.
- Adoption of these standards facilitates global trade and strengthens animal disease control measures.
