TGJB: Yeah, it\'s not like I\'ve talked extensively to Rick Arthur (probably number one in the field, having looked at the tests of thousands of racehorses, and treated almost as many himself as a practicing vet), or seen his studies. (As have you, I would add).

With the quarantine system you can duplicate lasix and other things that legally can affect CO2 levels, so that is a non-issue. If it is a \"false positive\", you will get it again, and the trainer will be off the hook.

TGJB: I had an extra minute so I took a look. The first thing the search showed is from Australia, where they don\'t use lasix. It said average was 30.77, and that the odds of a horse showing over 36 without help is 600,000 to one.
