Section 401.14 - Base excess prohibited levels

The prohibited Base Excess (BE) concentrations are as follows: BE level of 10.0 mmol/l (mEq/l) or higher for non-Furosemide (Lasix) treated horses and BE level of 12.0 mmol/l (mEq/l) or higher for Furosemide (Lasix) treated horses. The level of uncertainty will be included before it is considered a violation of these rules. The level of uncertainty is 0.4 mmol/l (mEq/l) and a positive test report must include this level of uncertainty. A horse must show a BE level of 10.4 mmol/l (mEq/l) or higher for a non-Furosemide (Lasix) treated horse and a BE level of 12.4 mmol/l (mEq/l) or higher for a Furosemide (Lasix) treated horse in order for a violation to be reported under this rule.
