Biologic variability in <scp>NT</scp>‐pro<scp>BNP</scp> and cardiac troponin‐I in healthy dogs and dogs with mitral valve degeneration

Abstract

High individuality of these cardiac biomarkers suggests that, following diagnosis, these assays are best interpreted by serial determination in individual canine patients rather than by comparison to a population-based reference interval. The smaller RCV values for dogs with mitral regurgitation suggest that smaller relative changes in NT-proBNP are clinically meaningful in these patients.
