Although higher levels of the aminotransferases, AST and ALT, in conjunction with higher levels of ALP and GGT may indicate hepatic injury and insufficiency [55], there were no other blood chemistry results (e.g. low GLUC, high BILT, increased WBC) or clinical signs (e.g. ascites, icterus) that were consistent with liver disease. This evidence concerns the gene GPT and liver disorder.
