Couldn't you draw the blood levels prerace and match them versus a baseline? If a horses prerace hematocrit level is off the charts then it would be scratched?

I think the cyclists do 50% level = a "positive" test.

In racehorses I like to see the levels over 40 though the "normal" range is usually called at 34-42. Sometimes in the summer we might see a higher level because of dehydration.
