The use of any foreign substance within 24 hours prior to post time of the race in which the horse is entered is strictly prohibited.

(c) Thoroughbred TCO2 levels: A blood serum or plasma TCO2 level shall not exceed 37.0 millimoles per liter in a non-Furosemide (non-Lasix) horse and not to exceed 39 mmol/L for a Furosemide (Lasix) horse.
