What this test is
Tumor markers are proteins, hormones, or other substances that can be produced by cancer cells or by the body in response to cancer. These tests measure the amount of one or more markers in a blood sample. Results are interpreted by a clinician in the context of symptoms, imaging, and other tests.
What it measures
- CA-125 — often elevated in ovarian cancer and some other conditions
- CA 19-9 — often elevated in pancreatic and other gastrointestinal cancers
- CEA — often elevated in colorectal and other cancers
- PSA — often elevated in prostate cancer and benign prostate conditions
- AFP — often elevated in liver and germ cell tumors
- hCG — often elevated in gestational trophoblastic disease and some germ cell tumors
- CA 15-3 — often elevated in breast cancer and some other conditions
- CA 27-29 — often elevated in breast cancer and some other conditions
What the test involves
A standard blood draw from a vein in the arm is the usual method for tumor marker testing. In some cases, a urine sample may be collected instead, depending on the marker being measured.
Why it is often ordered
A clinician may order tumor marker tests to help monitor a known cancer, assess response to treatment, or check for recurrence after therapy. They are not typically used alone to screen for cancer in people without symptoms.
Preparation
Preparation varies by the specific marker and the laboratory performing the test. Follow the collection lab's instructions, which may include fasting or timing the sample relative to treatment.
How results are reported
Results are reported as a numeric value for each marker, often with a reference range provided by the testing laboratory. Reference ranges differ between laboratories, so results should be interpreted using the range from the lab that performed the test.
