Although a test for EPO was developed in time for the games, no positive test for hGh was found. In March 2007, "L'Équipe", a French daily sports newspaper, reported on its website that Thorpe showed "abnormal levels" of two banned substances in a doping test in May 2006. The Australian Sports Anti-Doping Authority (ASADA) later confirmed that Thorpe was investigated for abnormal levels of testosterone and luteinizing hormone (LH); both naturally occurring in the body. Thorpe's elevated LH level was what caused ASADA to initially investigate, and dismiss, the test result. Thorpe denied the rumours in a press conference on 31 March 2007 stating, "I firmly believe I am clean, I have never cheated and have always fulfilled my obligations." In April 2007, the World Anti-Doping Agency (or WADA) issued a statement condemning the breach-of-privacy "L'Equipe"'s announcement constituted. Thorpe is prominent in the campaign against drug use, inside and outside sports. He has called for the introduction of blood testing, and criticised FINA for allegedly inadequate drug-testing procedures, claiming that "for anyone to think that they're swimming at a clean Olympic Games, they'd be naive". Although swimmers and coaches praised him, he was condemned by FINA, who accused him of bringing the sport into disrepute. Thorpe was selected by the United Nations to lead an anti-recreational drugs campaign in Japan, as well as promotional work for UNICEF for UN Children's Week.
