Sports cheats beware – if you thought your chosen method of blood doping was undetectable, think again.
That is the message sports officials are promoting after US cyclist Tyler Hamilton was nailed by a surprise test for a previously untraceable method of blood doping during the Tour of Spain race last week.
Hamilton, who won a gold medal at the Athens Olympics in August, denies any wrongdoing, and his backers are questioning the validity of the new test. But experts contacted by New Scientist believe the science is watertight.
