The effect of sodium bicarbonate and validation of beckman coulter AU680 analyzers for measuring total carbon dioxide (TCO) concentrations in horse serum.

This study evaluated the usage of Beckman Coulter AU680 analyzers for measurement of TCO in horse serum, and the effect of sodium bicarbonate administrations on serum TCO levels in resting horses. Treatment of horses with sodium bicarbonate did not result in any adverse events. Mean TCO concentration was significantly higher from 1 to 8 h in the sodium bicarbonate-treated horses compared to the untreated controls.
