KRT18 and metabolic dysfunction-associated steatohepatitis: More specialised biomarkers, such as cytokeratin‐18 (CK‐18: a marker of hepatocyte apoptosis and necrosis), reflect hepatocellular injury and are useful in distinguishing MASH from simple steatosis, while γ‐glutamyl transferase (GGT) has been associated with advanced fibrosis and mortality risk [145].
