Clinical Report: A Greener Route to Anti-Doping Analysis

Overview

A validated bar adsorptive microextraction (BAµE) workflow offers a lower-solvent alternative for confirming cocaine and its metabolites in urine. This method meets World Anti-Doping Agency (WADA) criteria, demonstrating no false positives or negatives.

Background

Cocaine is a commonly detected substance in anti-doping tests, but its low concentration in urine complicates confirmatory analysis. Effective sample preparation is crucial to concentrate target analytes and minimize interference from endogenous compounds.

Data Highlights

Key Findings

• The BAµE method showed no false positives in blank urine samples.
• No false negatives were observed in spiked samples.
• Validation was conducted against WADA criteria, confirming compliance.
• The method improved selectivity and sensitivity compared to traditional solid-phase extraction/GC-MS methods.
• The workflow is suitable for confirmatory testing rather than high-throughput screening.

Clinical Implications

The BAµE method complies with WADA standards for confirmatory testing of cocaine and its metabolites.

Conclusion

The BAµE workflow provides a lower-solvent alternative for anti-doping analysis.
