Tyler Hamilton Diary

The last month or so has been kind of a blur.

be prepared to head back to
Europe after the verdict in my USADA case. But when that didn?t go as planned, we pulled back a bit and just focused on keeping a decent fitness base (long rides but without much intensity). Now it?s time to regroup and step it up a bit. For those of you who are interested, our golden retrievers are doing well. Tanker and Anchor have been growing super fast and are really no longer puppies. Not too long ago, I was picking them both up at once. Now it is a chore just to lift one of them. We had a large fenced in yard built recently so they can no longer chase the local deer and squirrels. I can?t tell you how many times they had me riding after them on my mountain bike.

The fall out since the verdict in my USADA case has been an interesting read. If we?ve accomplished nothing else in this case, we will have put spotlight on the vanishing twin phenomenon. If you search ?vanishing twin? on the internet you?ll discover thousands of websites, and personal experiences about it. But in the mainstream world, I guess it?s still relatively unknown.

With regard to my case, the concept has been called ?a sign of the apocalypse? and listed under the ?News of the Weird?. The second story was later retracted after it was discovered it wasn?t so weird after all. I?ll be the first to admit that sounds kind of Sci-Fi. But, it?s real and it?s just one of the reasons we presented regarding how a healthy person could have a mixed blood population. One of our goals in the USADA hearing was to point out that the HBT test as it exists, is fatally flawed. The central problem with this test is that it makes the leap that a mixed blood population (detected through the method called flow cytometry), is there only because of a mismatched homologous blood transfusion. The defect in that theory is that flow cytometry, can indicate a mixed population when implemented correctly, but it doesn?t tell you why the mixed population is there.

In speaking with a number of experts from leading universities, hospitals, blood banks and laboratories around the world, we have been told that there are a number of reasons a person can have mixed blood populations. But this was never taken into consideration while the HBT test was being developed. In fact, there was never any sort of validation study conducted to support this test. We think this sets a very dangerous precedent. A new test would never be accepted by the medical community without rigorous scrutiny. It?s my contention that the standard should not be any different within the anti-doping community.

If this sounds like a diversion on my part, take this into account ? I did not transfuse blood from another person, yet I?ve been told I have a mixed blood population. So the question is ? how did my samples garner these results? WADA, the IOC, UCI and USADA all say
