Epidemiological studies have frequently associated PFASs, such as PFOA and PFOS, with elevated serum markers of liver injury (e.g., alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP)), non-alcoholic fatty liver disease (NAFLD) grading, staging, and histopathological severity [61,62,63,64]. Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
