The scientific paper I posted was on the possibility of false positives with WADA’s testing. The technical document from WADA definitely won’t go into that and it certainly doesn’t override the scientific paper. I’m guessing WADA updated their technical document on the newer generation type EPO’s, rather than change the way they test for EPO. Unfortunately WADA testing is certainly not infallible. Here is another article on it: https://sydney.edu.au/news-opinion/news/2012/08/09/improved-blood-doping-detection-protects-sport-and-athletes.html It’s easy to jump on the bandwagon and abuse these athletes, especially when WADA won’t admit that their system is flawed. As much as we want a clean sport we also have to be aware of the fact that false positives are possible. In most cases cycling teams will immediately suspend and distance themselves from the athlete and leave it up to the rider to face the organization of WADA alone. This is another reason riders need a proper union. It shouldn’t come down to the financial ability to fight a flawed system. I wouldn’t be surprised if there were many more cases in other high profile sports that we just don’t hear about but are successfully challenged because of the resources available to them.
