Plasma procalcitonin kinetics in healthy dogs and dogs undergoing tibial plateau leveling osteotomy.

Background: Procalcitonin (PCT) is a well-established biomarker for bacterial infection in human patients.

Objectives: We aimed to analyze the kinetics of plasma PCT (pPCT) in healthy dogs and dogs with canine cranial cruciate ligament (CCL) rupture undergoing tibial plateau leveling osteotomy (TPLO).

Methods: This prospective, longitudinal study included 15 healthy dogs and 25 dogs undergoing TPLO.
