<b>Agreement between a point-of-care analyzer and a reference laboratory analyzer for plasma phenobarbital quantification in dogs and cats</b>

This study suggests that caution should be exercised when using both analyzers interchangeably in clinical practice. In most cases from this study's population, the POC analyzer yielded higher phenobarbital concentrations. Clinicians should consider these discrepancies and interpret phenobarbital levels with caution, especially when switching analyzers during therapeutic drug monitoring. Further research is warranted to explore the causes of these differences and assess their clinical relevance in a broader population.
