To bring the Atlantic Provinces Harness Racing Commission (APHRC) in line with the International Federation of Horse Racing Authorities new TCO2 levels have been established by the APHRC, which will be effective May 1, 2021.

If the total carbon dioxide (TCO2) is equal to 36 mml/litre or higher, said horse will be considered to have a positive test. If said horse is competing on furosemide (Lasix) and has a TCO2 reading of 38 mmol/litre or higher this shall be considered a positive test.
