Direct and/or indirect bilirubin, hepatocyte integrity markers (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)), alkaline phosphatase (ALP), and gamma-glutamyltransferase (GGT) [118] and lactate dehydrogenase (LDH) [119,120] levels are reportedly higher in patients with COVID-19 [121,122], particularly in males. Here, GPT is linked to COVID-19.
