Tumor markers CEA (Carcinoembryonic antigen), AFP (Alfa-fetoprotein) in the serum were normal, yet CA (Carbohydrate Antigen)-125 was up to 86.14 U/mL (normal range <39 U/mL) and CA 19-9 was up to 54.54 U/mL (normal range <35 U/mL) suggesting significant elevation. Here, CEACAM5 is linked to neoplasm.
