Furthermore, we excluded SARS-CoV-2-related cholestasis based on: (1) the absence of viral RNA (PCR-negative at admission); (2) profound hyperbilirubinemia and progressive cholestasis inconsistent with COVID-19’s typically mild, self-limited hepatic injury (ALT/AST ≤ 3 × ULN; spontaneous resolution post-recovery) (27–30); and (3) the lack of correlation between liver injury and respiratory symptoms. This evidence concerns the gene GPT and COVID-19.
