Investigating the pathogenesis of high‐serum gamma‐glutamyl transferase activity in Thoroughbred racehorses: A series of case‐control studies

Abstract

We conclude that high GGT syndrome is likely a complex metabolic disorder and that viral hepatitis was not identified as a cause for this syndrome in this cohort of racehorses. Our results support a contribution of oxidative stress and cholestasis in its pathophysiology.
