Abstract
The accuracy of urine analyzers used for dogs and cats has remained uncertain. This study examines the agreement between results of urine analysis obtained using two devices marketed for animals and for humans and the results of quantitative biochemical analysis. The degrees of concordance for bilirubin and ketones in the same category were ~80%, but for pH these were only ~60% in dogs and cats. Degrees of concordance for protein and the UP/C ratio clearly differed between the devices for animals and humans. We found that values for bilirubin and ketones obtained using urine analyzers may be reliable, but pH is unlikely to be accurate enough to be clinically useful for dogs and cats.
