Red blood cell distribution width to platelet ratio in neonatal foals with sepsis.

Background: Rapid and accurate markers to aid diagnosis of sepsis are needed in neonatal foals. The CBC variable red blood cell distribution width (RDW) to platelet ratio (RPR) is associated with inflammatory response and linked to poor outcomes of sepsis in human patients.

Hypothesis: Explore the correlation of RPR with sepsis in neonatal foals and evaluate RPR predictive and prognostic value.
