SECTION 319.363. Testing for Total Carbon Dioxide

(a) Findings and Presumptions.

(1) The commission finds that a total carbon dioxide level of 37 millimoles per liter or more in equine serum can be achieved only through the administration, by any means, of a bicarbonate-containing substance or other alkalinizing substance.

(2) A horse entered or participating in a race may not be administered a bicarbonate-containing substance or other alkalinizing substance which causes it to carry in its body an excess level of total carbon dioxide.

(3) A positive finding by a chemist of total carbon dioxide level at or above 37 millimoles per liter in a race horse serum specimen is an excess level of total carbon dioxide and prima facie evidence that the race horse was administered a bicarbonate-containing substance or other alkalinizing substance in violation of this section.

(b) Testing Authorized. Testing for total carbon dioxide is authorized as listed below:

(1) The executive secretary may implement a program to collect specimens from race horses and test the specimens for the presence of total carbon dioxide. In a program implemented under this section:

(A) Specimens may be collected on a random basis, including randomly selected race dates, randomly selected races, and randomly selected horses; and

(B) Specimens may be collected prerace or postrace; or

(2) The stewards or commission veterinarian may require a horse serum specimen to be taken from any race horse designated for cause by the stewards or commission veterinarian for the purpose of testing for total carbon dioxide.

(c) Split Specimen.

(1) The commission finds that the postrace time period during which total carbon dioxide may be detected in a specimen taken from a race horse is limited. Therefore, to provide a meaningful split specimen program, the testing of a split specimen for total carbon dioxide must occur contemporaneously with the testing of the original specimen.

(2) To ensure the owners and trainers of race horses selected for testing under this section are given the opportunity for a split specimen, the trainer of record for each horse from which a specimen is taken pursuant to this section shall declare in writing whether the trainer requests that the split specimen be tested or waives the right to have the split specimen tested. Failure to request the split specimen test at the test barn within 30 minutes after the post time of the last race for the performance is deemed a waiver of the right to the split specimen.

(3) The split specimen shall be sent for testing to a commission approved and listed laboratory that is acceptable to the trainer of record. The commission staff shall arrange for the transportation of the split specimen in a manner that ensures the integrity of the split specimen.

(4) The trainer of record requesting the split specimen shall pay all costs of transporting and conducting tests on the split specimen.

(5) If the test on the split specimen confirms the findings of the original laboratory, it is a prima facie violation of this section.

(6) If the test on the split specimen does not substantially confirm the findings of the original laboratory, the stewards may not take disciplinary action regarding the test results.

(7) If an act of God, power failure, accident, labor strike, or any other event, beyond the control of the Commission, prevents the split from being tested, the findings of the original laboratory are prima facie evidence of the condition of the horse at the time of the test for total carbon dioxide.

(d) Conflict with Other Rules. To the extent that this rule conflicts with any other commission rule, this rule controls.
