python said:(i) the test for cera is a totally new test for the rome wada lab. they may be learning the ropes.
in your previous multiple posts you referred to WADA standards and procedures.RTMcFadden said:According to the CN article:
"CONI confirmed that the results of both the A and B sample analyses had been verified by the WADA-approved laboratory in Chatenay-Malabry, France. CONI's prosecutor will re-examine the case before deciding what further action can be taken"
Not quite sure what to make of that.
python said:hmmm, id wait before entertaining any conspiracy.
there could be a bunch of real circumstances causing the non-conformance.
i checked some probable facts effecting the conformance and they stand as follows.
(i) the test for cera is a totally new test for the rome wada lab. they may be learning the ropes.
(ii) if they analyzed urine sample in stead of blood (and i found no references to blood sample even on coni's own site) it would be an expected inconclusive result. just as for lndd at the time of cera test introduction in 2008 when they tested ricco's urine like 6 or 7 times before they got him. not much cera leaks into urine via the kidneys. too big of a molecule.
(iii) sample storage irregularities may cause some shifts in electrophoresis images. that is, basic isoforms vs. acidic
At the time of the competition and test, Rossi was the partner of Riccardo Riccò, and she is the mother of her son.
BroDeal said:(iii.b) The A sample was close to and just over the threshold for declaring a non-negative. The B sample came in just under the threshold.
I think the testers are currently claiming that the CERA in the urine sample degraded quicker than expected and a slight non-negative in the A sample became a slight negative in the B sample.
I have a limited background in Biochemistry, but I'm not an expert and I don't know anything about CERA-testing in particular. The way this usually works though, is that you have a detection agent that reacts with CERA and colours the sample, gives a crystalline product or somehow else allows you to detect it. The problem is that there might be other things that reacts with the detection agent, which would justify a testing threshold.luckyboy said:This is why the testing threshold sucks. How is there a threshold for something the body doesn't produce?![]()
craig1985 said:So how does this work? Do the CERA level's in Rossi's urine just enough in the A sample to make her test positive for CERA, but when the B sample is taken, it is not conclusive (ie borderline)?
Anybody remember Fabrizio Guidi (when he was riding for Phonak)? His A sample came back positive for EPO, but his B sample cleared him. That's the only other example I can think of.

Didn't Iban Mayó's B sample come back as being inconclusive when he tested positive to EPO in 2007?craig1985 said:So how does this work?

Mayo's case was different because the B sample was tested in Barcelona lab, somehow. But then it was resent to the Châtenay-Malabry in Paris, who confirmed that the B sample was positive. All had to do with differences in procedures used in the France Lab as compared with the Barcelona Lab. Here is the note from Wikipedia:Highlander said:I believe that it initially did, but some how they get testing him and ended up suspending him although I don't think that the Spanish federation agreed with it.
By the way, that is one of my pet peeves with this testing process. The head of the lab in Rome already stated that the A sample was conclusvie enough, so of course you have to think that they would attribute the failure to find proof to some sort of error. I imagine that just like Mayo they will test something else and within a month or two announce that Rossi is positive after all. However, when a rider challenges the testing process, they have no source of winning. It's just very inconsistent and they need to find some way to resolve it.
In 2007 Mayo rode for Saunier Duval-Prodir, taking his first Giro d'Italia stage win. On July 30, 2007, the UCI confirmed he had failed a test for EPO during the Tour de France, which he finished 16th .[2] On October 22, the Spanish federation cleared Mayo after a second test proved negative.[3] The UCI president Pat McQuaid stopped short of clearing the rider, pending further tests.[4] On December 19, a French laboratory confirmed the positive test.[5] In 2008, the Court of Arbitration for Sport upheld Mayo's two year's ban, which ended on 31 July 2009.[6]
