I'll repost the commentary I did on the Cobo case on a previous thread with the link to his UCI Anti-Doping Tribunal hearing.
Also, the ABP can
not detect microdosing of any ESA (i.e. EPO) nor small amounts of blood transfusions. So, as it stands now, riders can circumvent the ABP with microdosing. But microdosing
usually doesn't produce big improvements in performance. You would need to macrodose like they did back in the 90s when a rider could dope with impunity. And look at some of those incredible performances by riders like Riis & Pantani with their documented exceedingly high blood values.
If Pogacar has found some way of circumventing the ABP with macrodosing, I would think other riders would have eventually caught on.
>The Cobo case is strange indeed. According to UCI Anti-Doping Tribunal report, the ABP hematological-anomalies occurred during
both the 2009 & 2011 Vuelta, but were not reviewed & evaluated by the anti-doping expert panel
until July, 2014
The 09 Vuelta showed a high OFF-score sequence while the 2011 Vuelta show variability of RET% - both at 99% specificity (
less than 1 in 100 chance of being undoped). The expert panel concluded that in their opinion it was highly likely the anomalies were the result of the prohibited use of an ESA or method (transfusions).
According to the report, Cobo was sent an anti-doping rule violation notice in Aug, 2014 detailing the expert panel's findings, and given the opportunity to respond & offer an explanation. Typically athletes will try to explain the anomalies due to multiple reasons (e.g. altitude training/hypoxia exposure, dehydration, illness, prescription medication use, sample collection concerns, etc). This is where the expert panel will have to further evaluate & render a final decision - which can take quite a bit of time in many cases.
Cobo responded back with a list of explanations that needed to be reviewed. However, the report states that Cobo was "granted multiple extensions of deadlines failing to respond" where the Tribunal gave it's final decision not until
2019.
The report doesn't address the issue of the 3 year delay when the anti-doping experts evaluated the anomalies from the two Vueltas. Usually when there's an abnormal value or sequence of values on the ABP, it's immediately flagged by the system & forwarded to the anti-doping experts for evaluation. Why the anomalies weren't flagged during the Vueltas or why the delay
if they were flagged is still a mystery.
Here's the UCI Tribunal hearing report (PDF). It's very interesting on the timeline & the sequence of the events that led to Cobo's ban & DQ of both the 2009 & 2011 Vuelta results:
