Further blood laboratory data revealed normal electrolyte values, including sodium (137 mmol/L, reference range 135–145 mmol/L) and potassium (3.9 mmol/L, reference range 3.5–5.0 mmol/L), albumin (3.6 g/dL, reference range 3.5–5.5 g/dL), intact parathyroid hormone (48.1 pg/ml, reference range 15–68.3 pg/ml), creatinine (0.85 mg/dL, reference range 0.7 ~ 1.2 mg/dl), tumour markers, including carcinoembryonic antigen(CEA), carbohydrate antigen 199(CA199), alpha fetoprotein(AFP), prostate-specific antigen(PSA) and monoclonal band values. This evidence concerns the gene CEACAM5 and neoplasm.
