Scientists at the universities in Tübingen and Mainz have developed a test that can provide conclusive proof of gene doping. "For the first time, a direct method is now available that uses conventional blood samples to detect doping via gene transfer and is still effective if the actual doping took place up to 56 days before," Professor Perikles Simon, MD, PhD from Johannes Gutenberg University Mainz, Germany explained. "This represents a relatively low-cost method of detecting several of the most common doping genes," Simon stated in the presentation of the process.
