Biological passports for British athletes to curb dopingBritish anti-doping authorities will issue so-called biological passports to athletes of the country to deter further the use of banned substances before the London 2012 Olympics.

The scheme was announced by the UK Anti-Doping in collaboration with Britain’s only Wada-accredited laboratory at King’s College, London.

Every stage of the sample’s journey will be documented to avoid any wrongdoings.
