Advances in drug testing on the cycling scene may mean big changes for some at the Olympics.

A Fench lab working with the French Cycling Federation has come up with a test which is able to detect Erythropoietin (EPO) in athlete urine samples. Erythropoietin (EPO) is on the IOC list of banned substances.

It boosts the bodies production of red blood cells which carry oxygen. This can be a major advantage in sports like cycling, swimming, track and field and marathon running.

The French Cycling Federation has received approval from the International Cycling Federation to use the test at the upcoming Tour de France, France's biggest sporting event. The Tour has been rocked by several drug scandals in the last few years. The most notable 2 years ago when several riders failed drug tests and teams were caught with EPO in their possesion.

The new test will be presented to the IOC before Sydney but its not certain if it will be used approved for use.
