Overview
The laboratory tests that can be used for the diagnosis of colorectal carcinoma are the following: CBC, FOBT, serum CEA and CA 19-9 levels, serum iron levels, serum vitamin B12 and folate levels, 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 levels have a poor prognosis
- Low serum iron levels
- Low serum vitamin B12 and folate levels
- Hypercalcemia (with metastasis to the bone)
Test for Metastasis
- Abnormal liver function tests
- Abnormal pulmonary function tests
