From the Lab to the Court: Laboratory Techniques in Doping Detection and Their Legal Challenges

Doping in sports, defined as the unauthorized use of performance-enhancing drugs, is a critical issue in athletic competitions, with significant physical, ethical, and legal implications for athletes and sports organizations. This article aims to explore the types of doping substances, their analytical detection methods, and the associated legal challenges. This is a review study based on reliable scientific and legal literature. It first introduces various performance-enhancing drugs and their effects on athletes’ performance. Subsequently, the analytical methods, including Gas Chromatography-Mass Spectrometry (GC-MS), Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS), and immunoassay techniques, are examined. Furthermore, a comparative analysis is conducted on the legal challenges in Iran’s anti-doping regulations in comparison with those of the United States and international standards. The findings reveal that while analytical techniques such as GC-MS and LC-MS/MS are highly accurate and advanced, they require costly equipment and involve lengthy sample preparation. Meanwhile, immunoassay methods, due to their simplicity and lower cost, are effective for initial screening but are limited by the potential for false-positive and false-negative results. Legally, differences in national regulations and a lack of full alignment with international standards pose significant challenges to the effective enforcement of anti-doping laws. In Iran, the use of performance-enhancing substances is primarily regarded as a disciplinary violation and is only subject to criminal prosecution under specific conditions. Overall, to reduce sports fraud and enhance athletes’ health, the development of more accurate doping detection methods and the international harmonization of anti-doping legislation are essential. Additionally, establishing appropriate legal frameworks in Iran can strengthen the fight against doping and increase transparency in sports competitions.
