Below you will find a copy of an article published in the LA Times. To
be honest, I had given up on trying to explain my case to the media
some time ago, because it seemed no matter how hard I tried to correct
the misconceptions regarding my defense, few people were really
interested in listening. I had the chance to participate in this story
but didn't. I grew frustrated with speaking to folks only interested in
capturing a phrase or two that could be twisted and portrayed as
something else.
Ironically, of all the journalists who planted themselves in my living
room for up to 6 or 8 hours at a clip, had access to my legal team and
all of my experts -- none were able to summarize the central arguments
at the heart of my case better than Michael A. Hiltzik, a man I've
never met or spoken to in my life. He has written the article we had
hoped so many before him would write.
Cyclist blames 'flawed' test: Tyler Hamilton says the blood exam that labeled him a 'cheater' was rushed into use By Michael A. Hiltzik, Times Staff Writer
To anti-doping officials, the case against Olympic and Tour de France
cyclist Tyler Hamilton for an illicit blood transfusion ranks among
their greatest victories: a sanction for "intentional cheating at its
most sophisticated," in the words of Travis T. Tygart, general counsel
to the U.S. Anti-Doping Agency.
To others, including independent scientists who worked on Hamilton's
defense, it underscores one of the most glaring flaws of the
international anti-doping system - its reliance on scientific research
performed hastily and on the cheap.
The novel blood test used to condemn Hamilton as a cheater and suspend
him for two years was developed by researchers in Sydney, Australia, on
a $50,000 USADA grant - that sum is a fraction of what's normally spent
in medicine to develop and validate a diagnostic test.
"This test was not ready for prime time," says Carlo Brugnara, professor of pathology at Harvard Medical School.
Brugnara was a member of the peer-review committee that approved
publication of an article outlining the test in 2003. However, he felt
so strongly that it was prematurely implemented in Hamilton's case that
he volunteered to testify at an arbitration hearing for the cyclist in
2005.
Hamilton, a native of Marblehead, Mass., was considered one of
cycling's toughest and cleanest riders when he came under suspicion for
blood doping shortly before the 2004 Summer Olympics in Athens. He went
on to win the gold medal in the individual time trial.
At Athens, the World Anti-Doping Agency and the International Olympic
Committee had introduced a new field test that had to be fast-tracked
for the Games. Authorities feared a rash of prohibited blood
transfusions among endurance athletes seeking a boost from extra
oxygen-producing red blood cells.
At the Games, Hamilton's blood sample was declared negative, though
"suspicious" for blood doping, by WADA's Athens laboratory.
A month later, he was tested again at the Vuelta d'Espana, a grueling
Spanish race akin to the Tour de France. This time, authorities said
the test - performed by WADA's lab in Lausanne, Switzerland - had
identified a small concentration of foreign blood cells in his sample.
He was charged with doping.
Richard W. Pound, the WADA chairman, trumpeted the results as
vindication of suspicions in Athens. "We got him on the second bounce,"
he crowed.
On the surface, Hamilton's alleged violation made little sense.
Athletes seeking a blood-doping boost almost certainly would transfuse
from a stored supply of their own ? not only because it is nearly
undetectable in doping tests but also because it carries no risk of
illness or infection.
Indeed, use of another person's blood is so unlikely that one WADA
scientist speculated that Hamilton must have done it accidentally. "The
most likely scenario is that he meant to get his own blood but was
given someone else's," says Michael Ashenden, a member of the Sydney
team that developed the test.
Experts supporting Hamilton contend the concentration of purportedly
foreign cells in his blood at Athens and the Vuelta was too low to have
boosted his performance in those events and possibly too low to be
accurately measured.
They say the test results indicate that if Hamilton transfused at all,
it would have been more than two months before the Olympics, a wasted
effort, because performance-enhancing effects would have worn off well
before the Games.
"If someone was really doping, it would be really obvious," says David
Nelson, professor of cell and molecular biology at the University of
Rhode Island and a consultant on Hamilton's defense. "But these results
were wacky."
Hamilton declined to comment for this article. On his website, he calls
the tests "flawed and inaccurate" and says he "did not transfuse."
There is little dispute the test was rushed to implementation. Sydney
researchers had published results from trials on only 58 blood samples
using a process known as flow cytometry when WADA summoned them to
teach the technique to scientists at the Athens Olympics.
For any diagnostic test to be used in medicine, regulatory agencies
often require hundreds if not thousands of trials in a variety of
clinical and field settings to demonstrate reproducible results under
all conditions.
"It was appalling for me to see the low bar they set," said one of
Hamilton's expert witnesses, Dr. V.K. Gadi, a blood specialist and
oncologist at the Fred Hutchinson Cancer Research Center in Seattle.
"The way the test was designed and implemented would never pass muster
in any other regulatory situation."
During its first field application in Athens, the test encountered
problems. The lab failed a proficiency test just before the Games, lab
director Costas Georgakopoulos told The Times in an e-mail.
As a result, he said, he refused to certify Hamilton's sample as
positive for blood doping, a decision that infuriated his blood-testing
team. They considered the cyclist guilty.
With the lab's proficiency in question, Georgakopoulos said, "reporting
positive cases would endanger the whole Olympic doping control
program."
Meanwhile, on opening day of the Athens Games, Ashenden sent out a
blistering e-mail complaining that the Lausanne lab was "not yet
capable of performing the test to an acceptable standard."
He cited changes the lab had made in the test that might produce false positives.
Ashenden said in an interview that Lausanne had corrected all its flaws
before it examined Hamilton's sample from the race in Spain.
"Lausanne was keen to rush through the test, perhaps prematurely," he
said. "But it was only a matter of days before they started to get the
results we wanted to see."
One scientist testifying at Hamilton's hearing contended that
Australian researchers had not taken even rudimentary steps to
determine how susceptible their test might be to false positives. David
E. Housman, professor of biology at MIT, also told The Times in an
e-mail: "This process wouldn't cut it in the world of testing for any
medical condition."
Australian researchers had argued in published papers that false
positives "do not appear to be a problem," without showing they had
investigated the issue.
That seemed a "cavalier" dismissal to D. Michael Strong, chief
operating officer of Puget Sound Blood Center, a Seattle blood bank,
who testified for Hamilton.
"I don't know of a test that doesn't have false positives," he said in
an interview. Common scientific standards require developers of
diagnostic tests to identify and quantify the possible causes of false
positives, Strong said.
At Hamilton's first appeal of sanctions, arbitrator Christopher L.
Campbell issued a rare written dissent, citing "a number of bizarre and
inappropriate occurrences" in the case.
For example, soon after the Athens Games, anti-doping authorities
hand-picked an expert panel to reexamine Hamilton's Olympic sample. One
member was a developer of the controversial blood test, an arrangement
Campbell called a conflict of interest violating the "cardinal rules of
drug testing."
The panel did declare Hamilton's Athens sample positive. However,
because a confirmation sample already had been destroyed, the official
negative finding stood and the cyclist retained his gold medal.
Based on tests from the Spanish race, however, Hamilton was suspended for two years.
Campbell, highly critical of the entire test validation process, said
that the arbitrators' decision to accept the test despite its
deficiencies "establishes a dreadful precedent."
Hamilton's suspension ended in September, and he has resumed racing.
As for the feared crisis in blood doping that led to the crash
implementation of the test, WADA never found it. Only two athletes have
ever been declared positive, Hamilton and a second cyclist who chose
not to contest his sanction.
