We need to know a lot more about the BC testing before we can say it's a level playing field. Like: they are pulling blood pre-race, but doing the CO2 tests on it later. How long does the CO2 stay in the blood? And, are they going to publish the CO2 tests? If they don't, and the threshold levels stay as they have been (37-39), alkalizing agents can still be used as long as they keep it under that level. Publishing the test results will at least cause trainers to consider the bad publicity angle.

And this is aside from other issues that have been raised, like other drugs, testing arterial blood, etc...
