Assessment of markers such as hematological parameters (leukocyte, erythrocyte, hemoglobin, and platelet), biochemical markers (ALT, AST, UREA, CERA, fasting blood‐glucose, insulin, and C‐peptide), and tumor‐related markers (AFP and CEA) revealed no abnormal signs among subjects involved in this study (Table 1). This evidence concerns the gene GPT and neoplasm.
