Ask Big Boat if there are ways to deal with that.

Alpe d'Huez said:I can't honestly believe there are people out there that really think that the majority of riders are clean, and the UCI is doing a good job, and that this so-called biological passport program is the best possible way to test, and will succeed.
What sport have you guys been watching???
It's not my position to insult anyone. I have just posted time and time again my reasoning, with link after link after link to various peer reviewed reports, studies and cases, and I'm just not going to do it here. You're going to have to dig through the many other threads and posts on doping by myself and others, and do some of the same research on your own. If you want to ignore that and think the sport is clean and the UCI doing a great job, then well, all I can say is so be it.

luckyboy said:They just transfuse their own blood to up the hematocrit and then microdose something (what is it - hemopure now?) increase the retics don't they?
I'm no expert - just what I've kinda picked up
Epicycle said:Hematocrit is the amount of the blood red cells take up. So if you increase the plasma volume of the blood then the portion of the blood red cells account for decreases. It can be done with plasma expanders which are used in medicine to replace blood fluid in cases of shock, like in surgery. Also saline infusion is the most simple method to decrease hematocrit.
Epicycle said:I think you are getting confused here. You microdose EPO to avoid EPO tests. Microdoses can leave the body in as little as 6 hours. It makes no difference whether the EPO is in a blood bag or taken IV. The transfusion is given IV.
He was on CERA. If you are on an undetectable type of EPO and able to take large doses it might increase retics enough to foil the passport.

Google translated from Danish to English
he was just showing me where he saw what what kohl supposedly said.
i noticed something else in that article i found interesting.
Michael Ashenden, who one think by what's been said here could walk on water is mentioned as "one of UCI's experts on the biological passport"
elapid said:Hematocrit = packed cell volume. This is basically the percentage of red blood cells. As luckyboy said, the hematocrit can be artificially reduced by expanding the intravascular volume with either crystalloids (eg., saline) or colloids (eg., plasma).
Oxygen-carrying capacity is dependent on hemoglobin. Hemoglobin is only carried by red blood cells. Hemoglobin, and hence oxygen-carrying capacity, can only be increased by increasing the number of red blood cells (hence EPO and blood transfusions). There are products, such as Oxyglobin, which are artificial substances which allow sufficient oxygen-carrying capacity with a hematocrit as low as 2%. Rasmussen was implicated in using a similar product.
Reticulocytes are immature red blood cells. They are produced in the bone marrow to replace dead and dying red blood cells in circulation. Increased reticulocyte counts are a normal response to anemia, or low red blood cells. They are decreased with cancer and problems with EPO production, such as exogenous EPO (ie, doping) suppressing normal EPO production by the kidneys.
Alpe d'Huez said:I made a mistake in my last post. There actually is a test for HGH, but my understanding is that it's only effective within several hours after being administered in relatively high doses. So testers would have to get really lucky I guess to find someone positive, which is why no one has yet. Too tired to dig up links.
And yet riders continue to cheat the system, or the UCI is controlling the names of the riders that have failed to avoid scandal, which in concecuence beats the purpose of the "biological passport".OctaBech said:The cheaters have had it too easy for a long time but the methods mentioned are only viable with the loft values UCI set.The passport complicates doping a lot more because one will need to know the rider's values at the given time and the traced values/longitudinal graphs in the past.
That practically makes it impossible for the riders themselves to manipulate the stored blood to emulate the needed values to hide the transfusion.
OctaBech said:What simplify the scenario too much and should at least have mention that the passport not alone trace the density of red blood cells but also covers reticulocytes and haemoglobin.

OctaBech said:So the whole problem with cheating the biological passport is all the extra work one will have to put into it and the much minimized gain, the riders will have to be rich before being able to dope.
OctaBech said:I think there's a function in Google allowing one to sort away articles older than a year.
On a more serious note, the biggest problem with HGH has been the lack of out of competition test.
Though the passport can't directly identify HGH it does show the altered hormone ratio/(im)balance caused which allows for targeting the expensive HGH tests(luckily cheaper urine testing can soon become the norm).

Russian newspaper Nezavisimaya Gazeta states that Denis Mencov, Ivan Basso, Franco Pellizotti and (already caught) Antonio Colom are on the list of riders with suspected blood values
BroDeal said:Even though I like Pellizotti, this does not surprise me. He and Di Luca had a big mid career step up in performance.
The real fun will begin once we start hearing excuses. Those are always good for a laugh.
