CEA Blood Test to monitor cancer treatment response and detect recurrence.
Cancer marker blood tests measure substances produced by cancer cells or by your body in response to cancer. Common markers include PSA (prostate-specific antigen) for prostate cancer screening, CEA (carcinoembryonic antigen) used in colorectal cancer monitoring, CA-125 for ovarian cancer, and AFP (alpha-fetoprotein) for liver cancer. It's important to understand that tumor markers are not diagnostic on their own — elevated levels can have non-cancerous causes, and some cancers don't produce detectable markers. They are most valuable for monitoring treatment response, detecting recurrence, and as part of a broader screening strategy alongside imaging and clinical assessment.
Key Details
Who Is This For?
Men over 50 (or over 40 with family history) for PSA prostate screening. Anyone with a family history of cancer who wants baseline marker levels. Cancer patients monitoring treatment response or screening for recurrence. Health-conscious individuals incorporating cancer markers into their annual screening protocol.
What's Included
Preparation Required
No fasting required for most tumor markers. For PSA testing: avoid ejaculation for 48 hours before the test, avoid vigorous cycling for 48 hours, and don't test during a urinary tract infection — all can temporarily elevate PSA. Inform your provider of any recent medical procedures.
Biomarkers Tested
2Immunoglobulin E (IgE) is a protein associated with allergic reactions that is normally found in very small amounts in the blood. IgE functions as part of the body's immune system (its defence against 'intruders').
A protein produced by prostate cells. Elevated PSA can indicate prostate cancer, but also benign prostate enlargement, prostatitis, or recent ejaculation. PSA velocity (rate of change) and PSA density add diagnostic value.
