The MAIIA EPO Purification Gel Kit, 7D3-An Alternative Purification Kit for Screening and Confirmation Procedures

Area of Science:

• Sports Science
• Analytical Chemistry
• Biochemistry

Background:

• Erythropoietin-stimulating agents (ESAs) are prohibited substances in sports.
• Accurate detection of ESAs is crucial for maintaining fair competition.
• The World Anti-Doping Agency (WADA) sets strict technical guidelines for doping analysis.

Purpose of the Study:

• To evaluate the performance of the new MAIIA EPO purification kit 7D3.
• To confirm its compliance with the WADA Technical Document 2024 (TD2024EPO) for human urine samples.
• To assess its suitability for the purification of ESAs in doping control.

Main Methods:

• Validation of the MAIIA EPO purification kit 7D3.
• Testing for selectivity, reliability at minimum required performance levels (MRPLs), limit of detection (LOD), carryover, and recovery.
• Analysis of 81 urine samples for selectivity, 29 for reliability (MRPL, LOD), and 16 for recovery.

Main Results:

• The MAIIA EPO purification kit 7D3 demonstrated excellent selectivity and reliability.
• The kit met the minimum required performance levels (MRPLs) and limit of detection (LOD) criteria.
• Recovery rates were within acceptable ranges, confirming the kit's efficiency.

Conclusions:

• The MAIIA EPO purification kit 7D3 fulfills all criteria and requirements of the WADA TD2024EPO.
• The kit is a valid and reliable solution for purifying erythropoietin-stimulating agents from human urine for doping analyses.
• This advancement supports WADA's efforts in combating doping in sports.
