Overview
The laboratory findings associated with colorectal carcinoma are the following: CBC, FOBT, serum CEA and CA 19-9 concentration, serum iron concentrations, serum vitamin B12 and folate concentrations, liver function tests, and pulmonary function tests.
Colorectal Cancer Laboratory Findings
- 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
- Low serum iron levels - microcytic anemia
- Individuals over 50 years of age and with microcytic anemia are suspected of having colorectal cancer
- Low serum vitamin B12 and folate levels
- Hypercalcemia - with metastasis to the bone
Test for Metastasis
- Abnormal liver function tests
- Abnormal pulmonary function tests
