Detection of EPO injections using a rapid lateral flow isoform test

Area of Science:

• Sports Science
• Biochemistry
• Analytical Chemistry

Background:

• Recombinant human erythropoietin (rhEPO) misuse is a significant doping concern in competitive sports.
• Current detection methods for rhEPO doping have limitations in sensitivity and analytical throughput.
• There is a need for advanced diagnostic tools to enhance the detection of rhEPO abuse.

Purpose of the Study:

• To evaluate the efficacy of a novel lateral flow EPO isoform test kit, EPO WGA MAIIA.
• To assess the detection capabilities of the EPO WGA MAIIA test using plasma and urine samples from rhEPO-injected subjects.
• To compare the performance of the new test against indirect detection methods for EPO doping.

Main Methods:

• Evaluation of the EPO WGA MAIIA lateral flow test kit.
• Analysis of plasma and urine samples from eight healthy males undergoing a 28-day rhEPO injection regimen.
• Testing samples collected during and after the rhEPO administration period to determine detection windows.

Main Results:

• The EPO WGA MAIIA test demonstrated 100% effectiveness in detecting rhEPO during the injection period.
• Positive doping results were identified up to seven days post-injection, with 75% of subjects suspected at a 99% confidence limit.
• No rhEPO traces were detected 14 and 21 days after the last injection, outperforming previous indirect methods.

Conclusions:

• The EPO WGA MAIIA test is a highly effective tool for detecting rhEPO doping in athletes.
• Implementation of this user-friendly test can increase detection rates and analytical throughput in anti-doping efforts.
• The EPO WGA MAIIA test offers a significant advancement for initial screening procedures in anti-doping work.
