The World Anti-Doping Agency (WADA) has announced that it is very close to being able to implement the long awaited “Athlete Passport” system. It is hoped that the passport will provide testers with a lifelong “biological fingerprint” of competitors to compare drug-samples against and will be a key component in the central ADAMS (Anti-Doping Administration & Management System) Database. More details of ADAMS can be found here: http://www.uksport.gov.uk/pages/adams/
Any anomalies in blood chemistry, such as raised haemoglobin levels (associated with EPO abuse) or other biological disturbances would then allow further tests to be conducted and potential cheats identified at a much earlier stage than at present.
The idea has been pioneered by the International Cycling Union (UCI), the Federation Internationale de Skiing (FIS) and the International Amateur Athletics Federation (IAAF), and further trials of the scheme will take place at the World Athletics Championships in Berlin this summer.
Although the UCI has been at the forefront of piloting the passport scheme, and last year took 8,300 blood samples from 804 cyclists, its efforts are not currently being supported by WADA, after the UCI President sued WADA following a row over Floyd Landis’s appeal against his doping ban. http://www.uci.ch/Modules/ENews/ENewsDetails.asp?id=NjE5MQ&MenuId=MjI0NQ&BackLink=%2Ftemplates%2FUCI%2FUCI5%2Flayout.asp%3FMenuId%3DMjI0NQ
