GPT and End Stage Liver Disease: The most widely accepted definition of EAD, proposed by Olthoff et al. [6] in a model for end-stage liver disease (MELD), is based on the presence of one or more of the following criteria: serum total bilirubin ≥ 10 mg/dL on postoperative day 7, international normalized ratio (INR) ≥ 1.6 on day 7, or aspartate aminotransferase (AST) or alanine ami-notransferase (ALT) > 2000 U/L within the first 7 days.
