Measurement uncertainty in anti-doping quantitative analysis for prohibited threshold substances

Area of Science:

• Analytical Chemistry
• Sports Science
• Regulatory Compliance

Background:

• World Anti-Doping Agency (WADA)-accredited laboratories operate under strict performance standards.
• These standards, detailed in WADA's International Standard for Laboratories and Technical Documents, ensure valid test results and data.
• Accurate determination of anti-doping rule violations relies on quantitative analyses and specific compliance decision rules.

Purpose of the Study:

• To review and discuss the application of measurement uncertainty in establishing WADA's compliance Decision Limits.
• To evaluate laboratory performance over time and comparatively using WADA's External Quality Assessment Scheme.
• To provide insights into challenges in harmonizing quantitative measurements of large biomolecules.

Main Methods:

• Review of WADA's International Standard for Laboratories and Technical Documents.
• Analysis of measurement uncertainty in the context of compliance decision rules.
• Discussion of WADA's External Quality Assessment Scheme for laboratory performance evaluation.

Main Results:

• Measurement uncertainty is crucial for setting scientifically sound Decision Limits.
• The External Quality Assessment Scheme effectively monitors laboratory performance and facilitates inter-laboratory comparisons.
• Harmonizing quantitative measurements for large biomolecules presents ongoing analytical challenges.

Conclusions:

• Effective use of measurement uncertainty enhances the reliability of anti-doping test results.
• WADA's quality assurance programs are vital for maintaining high laboratory standards.
• Addressing emerging challenges in biomolecule analysis is essential for future anti-doping efforts.
