Carcinoembryonic Antigen (CEA) Blood Test
£48.00
Monitor oncology treatment response and disease progression with a private Carcinoembryonic Antigen (CEA) blood test at Medical Diagnosis Victoria (MDX Victoria) in London.
This test measures the concentration of carcinoembryonic antigen circulating in your bloodstream, a vital glycoprotein tumour marker widely utilised across clinical oncology. While primarily used for the ongoing surveillance and monitoring of colorectal cancer, CEA testing also provides essential biochemical data during the follow-up of breast, lung, or pancreatic malignancies to evaluate how effectively a tumour is responding to therapy.
With a 5-day turnaround, this specialised screening delivers the reliable diagnostic insights your doctor needs to track treatment outcomes, identify early recurrence, and guide targeted oncological care.
Oncology & Tumour Marker Surveillance
Private CEA Blood Test in London
Carcinoembryonic Antigen (CEA) is a highly valuable diagnostic biomarker used extensively in clinical oncology, particularly for the management of colorectal malignancies. At Medical Diagnosis Victoria (MDX Victoria), we provide a private CEA blood test to help specialists and patients accurately track treatment response, monitor post-surgical recovery, and evaluate complex gastrointestinal conditions. Our clinical practitioners in central London deliver compassionate, discreet care with comprehensive laboratory results available within 5 days.

Diagnostic Focus
What is the Carcinoembryonic Antigen (CEA) Test?
Carcinoembryonic Antigen (CEA) is a glycoprotein involved in cell adhesion that is normally produced in high amounts during fetal development. After birth, production drops significantly, leaving only trace amounts in the blood of healthy adults. However, certain types of cancer—most notably colorectal (bowel) cancer, but also lung, breast, and pancreatic cancers—can cause cells to begin producing CEA again. Measuring circulating levels provides oncologists with critical objective data to assess tumour activity and therapeutic success.
Colorectal Monitoring
Evaluating this biomarker helps to:
- Establish a baseline prior to bowel surgery
- Monitor the effectiveness of chemotherapy
- Detect early recurrence post-treatment
- Support broader gastrointestinal diagnostics
Broader Oncology Assessment
This test is highly useful because it:
- Tracks specific types of lung cancer
- Assesses advanced breast cancer response
- Monitors certain pancreatic conditions
- Complements other specific tumour markers
Therapeutic Tracking
The laboratory provides critical data to:
- Evaluate overall disease stability
- Detect microscopic disease spread (metastasis)
- Guide ongoing multidisciplinary care plans
- Provide reassurance during survivorship
Clinical Uses
Why is Blood Testing for CEA Important?
Tumour markers serve as a biochemical footprint of cancer activity. While imaging scans like MRIs or CTs show the physical size of a tumour, serial testing of CEA shows its biological behaviour. This enables healthcare teams to make highly informed, prompt decisions about whether an active treatment plan is working or needs adjustment.
Pre- & Post-Surgical Evaluation
For patients newly diagnosed with colorectal cancer, doctors will almost always check CEA levels before surgery. The clinical goals are:
- Baseline Measurement: Knowing the pre-surgery level helps determine the aggressiveness of the tumour.
- Surgical Success: Following a successful tumour resection, CEA levels should drop back to normal within a few weeks. If they remain elevated, it may suggest that not all malignant tissue was removed or that it has spread.
Long-Term Post-Treatment Surveillance
Following successful treatment and remission, the CEA blood test is a cornerstone of survivorship follow-up:
- Routine testing is typically performed every 3 to 6 months for the first few years after colorectal cancer treatment.
- A steadily rising CEA level can be the very first indicator of cancer recurrence—often rising months before new tumours are large enough to cause symptoms or appear on scans.
Important Note on Cancer Screening
The CEA test is an incredibly powerful tool for managing known cancers, but it is not used as a general screening tool for healthy individuals. Early-stage bowel cancers frequently do not produce enough CEA to raise blood levels, and heavy smoking or benign inflammation can cause false positives. Diagnosis always relies on colonoscopy and histological biopsies.

Pathology Reports
How To Read Your Laboratory Results
Your report will display your serum CEA concentration, usually measured in nanograms per millilitre (ng/mL). Normal reference ranges are generally low (typically < 3.0 ng/mL for non-smokers, and slightly higher for active smokers). Mild elevations can occur in benign digestive conditions like ulcerative colitis, pancreatitis, or liver disease. However, progressive or markedly high results strongly suggest an active malignant process. Specialists interpret CEA results primarily by assessing the trend over time rather than relying on a single isolated reading.
Results Timeline: Your specialist diagnostic report is typically available within 5 days of your blood draw.
Medical Consultation
Need Help? Private GP Consultations
Tumour markers require experienced medical evaluation. If your CEA result is unexpectedly elevated or shows an upward trend, or if you are troubled by persistent gastrointestinal symptoms, our private GP service is available on site. Our clinicians can interpret your results, arrange complementary blood or stool tests (such as Calprotectin or FIT tests), and facilitate urgent referrals to consultant gastroenterologists or oncologists.

Frequently Asked Questions
Do I need to fast before a CEA blood test?
No special fasting is required before a CEA blood test. You may eat and drink normally prior to your sample collection. However, you should inform your doctor if you smoke, as smoking can naturally elevate baseline CEA levels.
What is the CEA test most commonly used for?
The CEA test is the gold-standard tumour marker for monitoring colorectal (bowel) cancer. It is used to establish a baseline before surgery, track the success of chemotherapy, and monitor for any signs of cancer recurrence during long-term follow-up.
Can non-cancerous conditions cause elevated CEA?
Yes. While CEA is a prominent tumour marker, several benign conditions can also cause elevated levels in the blood. These include inflammatory bowel disease (Crohn’s disease and ulcerative colitis), liver cirrhosis, chronic lung infections, and heavy tobacco smoking.
How quickly will I receive my CEA test results?
Because this specialised tumour marker assay is performed by our accredited referral laboratory with stringent quality and calibration controls, your comprehensive diagnostic report will be securely delivered within 5 days.
Is the phlebotomy fee included in the £48.00 price?
No, the £24.00 phlebotomy service fee is separate. It covers the expert clinical blood draw performed by our qualified practitioners at our central Victoria clinic.

Most Searched Online Questions About CEA
Why do smokers have higher CEA levels?
Tobacco smoke contains thousands of chemicals that irritate and inflame the respiratory and gastrointestinal tracts. This chronic cellular irritation causes normal tissues to produce higher baseline levels of Carcinoembryonic Antigen compared to non-smokers.
Is CEA testing used for lung or breast cancer?
While colorectal cancer is its primary focus, CEA is sometimes elevated in advanced lung, breast, medullary thyroid, or pancreatic cancers. In these selected cases, oncologists may use it as a supplementary marker to monitor metastatic spread or treatment efficacy alongside specific markers (like CA 15.3 for breast cancer).
Can CEA determine what stage my cancer is?
Not precisely on its own, but there is a strong correlation. Extremely high levels of CEA prior to surgery are often associated with more advanced disease stages or a higher likelihood of the tumour having already spread (metastasised) to other organs, such as the liver.
