Child-Pugh clinical classification

Child-Pugh clinical classification scheme (Table 7.5). Serum albumin concentrations were of greatest predictive value for two of the drugs shown in the table. However, this marker was not correlated with the hepatic clearance of lansoprazole, and a combination of all three laboratory tests was better correlated with hepatic clearance of atorvastatin than was serum albumin alone. Serum concentrations of aspartate aminotransferase (AST) or alanine transaminase (ALT) were not correlated with hepatic drug clearance, as might be expected from the fact that these enzymes reflect hepatocellular damage rather than hepatocellular function.
