RE: [RC] Drug testing - detection and sample size - heidiI think you'll find that most of the random samples are taken in the top ten. If we want to uncover drug use taking samples from the horses that the vets suspect, rather than randomly would give us more results for our testing dollar. Libby The procedure used by the testers at the rides that I've vetted has been a good one, IMO. They would test 5 horses, and while the horses were still out on the course, they would randomly pick the finish order of the horses they would test. They would put the numbers 1-10 in a hat, and then the numbers 11-whatever the number of starters was in another hat. If it was a small ride, they would draw three from the top ten and two from the other hat. If it was a really big ride, they would draw 2 from the top ten and 3 from the other hat. So the top ten did get a higher percentage tested, but there was also random testing of the rest of the pack. The testers wouldn't arrive until the horses were well out on the course, so the riders didn't know in advance that they were there. But by sampling the rest of the group, they also prevented somebody from slowing up to get OUT of the top ten to dodge testing, if perchance they DID find out in advance that the tester was there. When I worked on the track, the protocol was two horses from every race--the winner, and one randomly from the rest of the pack.
