The patient's test results lacked specificity, with bilirubin at 4.6, glutamic oxaloacetic transaminase (GOT)/glutamic pyruvic transaminase (GPT) at 25/11.3, alkaline phosphatase (ALP)/gamma-glutamyl transferase (GGT) at 80/77, and tumour marker values of CA-19 at 65.6 U/mL (reference range, 0-35 U/mL). This evidence concerns the gene GPT and neoplasm.
