GPT and COVID-19: Hepatic injury in COVID-19 patients can be assessed using liver biochemical tests: serum albumin, cholestasis markers-bilirubin, gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), liver transaminases-aspartate aminotransferase (AST/TGO), and alanine aminotransferase (ALT/TGP) [27,28].
