At first the B - test was negative. It was said in every newspaper and in every source available. Well, there is a chance the media made it from "not readable" or inconclusive to negative, but normally the media is not on hand of the presumed doper...
But lets say the test in Ghent was indeed inconclusive. Well, I actually quite never heard from inconclusive tests before and also not afterwards. Ghent sent it to Sydney, which confirmed they couldn't read it. Strange, because the test consists of some numbers and some diagrams and normally you never hear that there is a problem reading it. So my conclusion is: a. they messed up the B - sample. b. They tested it negative but under pressure of the UCI they changed it to inconclusive so the test could get back to the infamous Paris lab or c. The test was inconclusive in the first place.
Considering the other innormalities this case contains I personally go for option B, with holding option C open. What does it mean when option C is the truth? An inconclusive test. Well maybe it can happen but like I said I have my doubts. But when a test is indeed inconclusive, you are going to test it again. Sounds fair for a start. But why test it again in another lab? There is no reason whatsoever why they should do that. There is no single valid argument. By saying that the Paris lab has more possibilities in testing it becomes clear that the riders are not equally treated (which is actually true, I advice you to read the book of Landis) and that the Paris lab has different testing methods. The Paris lab is a lab which has a bad name in the sport world, multiple mistakes happened there in the past and the personnel is not well trained and equipped to work with the stuff in there. I'd call that at least dangerous. So sending the test to another lab would make no sense at all if the UCI is consequent (which they aren't because they did). That's why I choose for option B. The test was negative in Belgium and this was confirmed in Australia. Via a source this came in the media and the UCI didn't want that. The only thing they could say was that the testing was not yet completed (and while saying that, the result was inconclusive. Strange, an inconclusive result but the testing was not completed yet) and that they needed more time to get the test positive, because the UCI hates nothing more than apologizing for their own faults or confirming one of their tests and labs doesn't work. Saying that would give a mess in the sport world and UCI and WADA would lose control, and of course the bosses of the bureaucratic organisations don't want that. The same happened with the Landis case. It was so obvious that the testing was malicious like hell but the CAS didn't listen and said he was still positive because otherwise the whole anti doping sport business would be lost and out of control.
So this is how the occassional sporter gets punished for something he didn't use, to keep everyone quiet... Now we are only talking about that mad Landis and who cares about a single person. In the other case we would question all the tests and for the bigger picture some riders are sacrificed.
I know this is a story of ifs and buts but I have thought about this for years and the experiences of for example Mayo and Landis (among others) confirmed my thoughts. And now the same is happening to Astarloza.
