Lance Armstrong is cheating?

This month, some of the favorites to win the Tour de France cycling race of resistance have been introduced because of the suspicion of having taken drugs or blood transfusions prevented to increase their red blood cells. This leads the charge of Lance Armstrong, probably the dominant resistance cyclist of all time, took the drug in the blood increases when the first of his seven Tour de France victories won.

The accusation is that the urine of Lance Armstrong kept inStorage for six years, had raised a positive test for EPO, a drug that limits blood levels of hemoglobin and oxygen transport to boost performance. An article in the latest issue of the prestigious medical journal published in Blood (June 15, 2006) shows that after the race in a sporting event, the athlete may have a false-positive urine test for EPO.

The test for EPO will be carried out by means of protein, EPO, into animals so that their bodies produce special proteins calledAntibodies, which attach to EPO. The antibodies are placed on a special dish, and added to the urine test. The urine contains EPO, a band composed of the EPO antibody bound to appear on a special plate.

Researchers at the Catholic University of Leuven in Belgium have shown that "this test may occasionally spread of false positive detection of EPO results in additional burdens, high protein in urine. Every athlete can cause a false-positive tests by this method. Most people with healthyKidneys are not paid protein in urine, but after intense exercise, athletes with normal kidneys often paid protein in their urine. For example, paid more than 80 percent of the runners of protein in urine after running the Boston Marathon. The authors suggest that antibodies that can be used in the test, a protein in the urine, not only for the number of EPO.
