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.

FAQ
Frequently asked questions
Can tumor marker tests diagnose cancer on their own?
No. Tumor marker tests alone cannot diagnose cancer. They are used with other tests, such as imaging and biopsy, to help evaluate a person's condition.
Do elevated tumor marker levels always mean cancer?
No. Many non-cancerous conditions can raise tumor marker levels. A clinician interprets results alongside symptoms, medical history, and other test findings.
Are tumor marker tests used for screening in people without symptoms?
Generally, no. These tests are not recommended for routine screening in people without symptoms because they can produce false results. They are more often used to monitor known cancer or assess treatment response.
How long does it take to get tumor marker test results?
Turnaround time varies by the laboratory and the specific marker being tested. Many results are available within a few business days, but your ordering provider or the lab can give you a more precise timeframe.
