BBC News "Organisers of the London Olympics are determined to keep the games drug-free. Scientists have developed tests to detect nearly every type of doping in sport, but they have not yet perfected a way to prevent all forms of the banned practice of blood doping. It involves athletes storing and transfusing their own blood - or the blood of others - before exercise or competition, to increase the number of red blood cells in the body. By manipulating their oxygen-carrying capacity, cheats can increase their stamina and speed. It is possible to detect some - but not all - types of blood doping."
If you do some research into how fighters are tested in boxing compared to other sports, you realize that the doping tests in boxing is completely archaic. Boxing really needs to do some improvement on that aspect of the game.
