Laboratory findings in patients with small intestine cancer include:[1]
- Complete blood count and differential count – anemia
- Fecal occult blood test (FOBT) – demonstrates occult bleeding from the intestines
- Serum carcino-embryogenic antigen (CEA) and CA 19-9 – elevated concentrations are associated with large tumor masses, and have a poor prognosis
