Tyler's blood test: feto-maternal haemorrhage
http://www.theaustralian.news.com.au...5E2722,00.html
Sydney test hauls in its first victim Jenny McAsey September 23, 2004 ANOTHER door has slammed shut on sport's drug cheats. A doping test developed by Sydney-based researchers and introduced secretly during the Athens Olympics has produced evidence that gold medal-winning cyclist Tyler Hamilton had had an illegal blood transfusion. If the case is confirmed, it will mark the first time sporting authorities have officially detected blood doping. The practice has been used for more than three decades to boost performance in endurance events such as cycling and distance running. "We've closed another avenue for athletes to dope," said Dr Michael Ashenden, the co-ordinator of the Australian consortium that developed the blood doping test. "Sooner or later they will get the message that when we say we are going to bring in new tests and keep samples and analyse them, it will get through and that has to be good news for the clean athletes. If this marks the day where that really began to sink in, that is a positive." Hamilton, a 33-year-old American who won the Olympic time trial race in Athens, reportedly has been notified by the International Olympic Committee and international cycling officials that two separate tests showed evidence he had received a transfusion of blood that wasn't his own. One test was conducted on August 19, the day after his Olympic victory, while the second was done at the Tour of Spain where Hamilton won a stage two weeks ago. Hamilton yesterday held a news conference in his home base of Switzerland to vigorously dispute the results. He said he was "100 per cent innocent". His 'B' blood samples have not yet confirmed the result. Hamilton could lose his Olympic gold medal and face a two-year ban if his B sample from Athens tests positive. Australia's Michael Rogers, who was fourth in the time trial, would be given the bronze medal. The world-first blood doping test used at the Olympics was developed by Margaret Nelson at Sydney's Royal Prince Alfred Hospital over the past two years. While Hamilton's supporters yesterday questioned the validity of the new test, Ashenden, who oversaw the research, said it was very reliable. "The test has been used for a decade in hospitals to detect feto-maternal haemorrhage - if they get it wrong it is a life or death situation," Ashenden said yesterday. "They don't get it wrong; the test works. "If the sample shows positive then that person has someone else's blood in their circulation, there is no question, there is no doubt, there is no grey area." Before the Olympics, the World Anti-Doping Agency and the IOC came to an agreement with RPA Hospital to implement the test. While WADA head Dick Pound had warned athletes new tests would be introduced at the Olympics, he didn't say which ones. "That test wasn't announced quite deliberately," Ashenden said. He said the Australian researchers were proud to have played a part in stopping what was "a terrible practice" among athletes. "It is life threatening," Ashenden said. "In a hospital setting doctors won't give a transfusion unless they absolutely have to because of the inevitable risk, and for an athlete to be doing that in a hotel room without any genuine reason is ludicrous." The doping method involves an athlete injecting a quantity of blood from another person with the same blood type. The result is a boost to the red blood cell count, which increases the body's oxygen-carrying capacity, and thus endurance. The head of the Australian Sports Drug Agency, John Mendoza, said it gave unethical athletes a clear advantage. "The increases that can occur from boosting one's red blood cell count can be up to 15 per cent in terms of endurance capacity," Mendoza said. "It is highly dangerous. It increases the risk of stroke dramatically." Blood doping is thought to have begun in the 1960s when athletes withdrew some of their own blood, stored it and re-injected before competition when their body had already replaced the missing blood. At the 1972 and 1976 Olympics Finnish distance runner Lasse Viren won the 5000m and 10,000m track events. He was accused of pioneering blood doping, which became illegal in 1986. In the 1990s erythpoietin, or EPO, took over as the doping method of choice for endurance athletes. It had the same effect as transfusion but was simpler and cleaner to use. But Mendoza said blood doping had come back into vogue after a test for EPO was introduced at the Sydney Olympics. There is still no test for transfusion using an athlete's own blood (which is not as common), but Ashenden said more research was underway. "In 18 to 24 months I hope we will be in a position to detect where an athlete blood dopes with anything at all, and that will be a very important day for sport." |

Sydney test hauls in its first victim
Jenny McAsey September 23, 2004 ANOTHER door has slammed shut on sport's drug cheats. A doping test developed by Sydney-based researchers and introduced secretly during the Athens Olympics has produced evidence that gold medal-winning cyclist Tyler Hamilton had had an illegal blood transfusion. Lance was smart not to compete in the Olympics. Look at what happened to Tyler, off of Phonak, 2 year suspension, end of career, at your local LBS in a year or two to try to sell you some zero pedals. |

It could well explain the absence of several riders in Athens. Next year might be more interesting in a sporting sense. Now if only they could find a way to test for autologous transfusions. Lets hope they increase the out of competition tests as well. So , perhaps the way this past year to make the pig fly was autologous transfusion combined with thg/steroid stacking. Now who would do that, Henry?? |

The test appears valid as it has been used 10's of thousands of times
over the last 10 years according to the article. Tyler should protest (as they all do) and go ahead and enjoy retiring in his early 30's rather than get his ego all involved and fighting until his last Euro. Alternatively, he could write a tell all book, cash in for millions, testify in court and nail the rest of them. |

It justs keeps getting stranger as now Phonak has announced that the IOC "B: test came back negative and that the Vuelta "B" test came back positive which they say backs the claim that the tests currently as performed and based on percentages are unrealiable. If the above is true I guess he could keep his gold and no suspension but he would be suspended for the Vuelta infraction. This whole thing just leads to more confusion adn doubt which is raised to higher levels by the long delay (1 month) in announcing the IOC results in the first place. It looks from the outside (as I have no inside information) that when the IOC got the first positive they were unsure of the test and it's results and used (by forewarning UCI and Vuelta officials) of the positive test and used the Vuelta positive as second test to prove their test. Which is now foiled by the fact that the IOC positve is contridicted by the IOC "B" test negative but supported by the UCI "B" test positive. Once again from the outside and not being all knowing as some on the board and just taking information from what I have read on various sites I think this does show that this particular test is in need of refinement to determine doping. I know the invetor has claimed that the test is relaible as it used to test for a feto-maternal haemorrhage. However by using probability if the test show showed a 80% (or even less such as 50%or even lower) percent chance of a haemorrhage of course the doctors would act in the best interest of the mother and child andor perform more tests or emergency procedures and it would save lives 50% of the time and the procedures while an increase risk in the pregency may not be be as severe as the risk of a haemorrhage. However is that same percentage of 50-50 enough to end a persons reputation and/or career. Just thoughts as I am no expert and it will be interesting to watch the developments over the next weeks and months. -- hawkes |

It took them forever to get this test approved and now, after a big
name gets busted by it we hear its no good!? Come on! Personally I would be very disappointed, even sad, if Tyler gets busted but I've heard he was on "the program" for a while like pretty much everyone else. Maybe its all a bad dream, but I don't know how they're going to explain away two (or more tests). Sure, he might get away without a ban because of some technicality or legal wrangling but we'll all know the truth. They should retest all his results this year (if they have the blood), or test him again over the next 3 months. Then we'll see. That won't happen either. One more down... CH "B.
