CA 72.4 Blood Test
£80.00
Evaluate gastric and ovarian tumour marker activity with a private Cancer Antigen 72.4 (CA 72.4) blood test at Medical Diagnosis Victoria (MDX Victoria) in London.
This test measures the level of cancer antigen 72.4 circulating in your bloodstream, a specialised glycoprotein marker primarily associated with the digestive and female reproductive systems. Evaluating this biomarker is highly valuable for supporting the assessment of gastric (stomach) cancer, monitoring ovarian cancer in select clinical cases, and tracking disease progress during oncology follow-up for gastrointestinal malignancies.
With a 7-day turnaround, this specialised screening provides the reliable clinical data your doctor needs to support complex oncological evaluations and guide targeted medical management.

Diagnostic Focus
What is the Cancer Antigen 72.4 (CA 72.4) Test?
Cancer Antigen 72.4 is an antigenic mucin-like glycoprotein complex (TAG-72) expressed in high concentrations on the surface of adenocarcinomas, particularly of the stomach, gastrointestinal tract, and ovaries. In healthy adults and benign tissues, expression is minimal. When malignant changes occur in gastrointestinal or gynaecological tissues, excess CA 72.4 is released into the systemic circulation. Measuring circulating levels provides oncologists and gastroenterologists with targeted biochemical insight to corroborate imaging and clinical findings.
Gastric Malignancies
Evaluating this biomarker helps to:
- Support the diagnosis of gastric cancer
- Assess upper gastrointestinal mass lesions
- Evaluate suspected stomach adenocarcinoma
- Complement endoscopy and CT evaluations
Ovarian Assessment
This test is highly useful because it:
- Monitors mucinous ovarian carcinomas
- Serves as a secondary marker to CA 125
- Evaluates complex pelvic or adnexal masses
- Assists in staging ovarian malignancy
Oncology Surveillance
The laboratory provides critical data to:
- Track response to chemotherapy regimens
- Assess surgical clearance following resection
- Detect disease recurrence in follow-up
- Support multidisciplinary cancer care
Clinical Uses
Why is Blood Testing for CA 72.4 Important?
Early symptoms of gastric and ovarian diseases are frequently insidious, often mimicking benign functional dyspepsia, gastritis, or irritable bowel syndrome. While standard imaging remains fundamental, tumour markers like CA 72.4 provide an objective biochemical baseline that reflects tumour burden, cellular differentiation, and therapeutic responsiveness.
Evaluating Persistent Upper GI & Pelvic Symptoms
Clinicians may consider investigating CA 72.4 in selected clinical scenarios, such as when patients present with persistent or unexplained signs requiring specialist workup:
- Unexplained, persistent indigestion, early satiety, and progressive upper abdominal discomfort.
- Significant unexplained weight loss, chronic nausea, or difficulty swallowing.
- Pelvic or adnexal masses where standard tumour markers (such as CA 125) are equivocal, particularly when mucinous ovarian histology is suspected.
Post-Treatment Surveillance & Recurrence Monitoring
In patients with confirmed gastric or ovarian tumours, serial CA 72.4 testing plays a defined clinical role in:
- Monitoring therapeutic efficacy during active chemotherapy or targeted oncological therapy.
- Detecting early relapse: a consistently rising CA 72.4 titre can precede clinical or radiological recurrence, prompting timely re-evaluation.
- Combining with CEA and CA 19.9 to maximize sensitivity in gastrointestinal cancer surveillance.
Understanding Gastrointestinal & Ovarian Health
A quantitative CA 72.4 blood test provides essential diagnostic clarity in specialist oncology care. For further clinical guidance on recognizing upper gastrointestinal symptoms in the UK, consult the official NHS guide on stomach cancer.

Pathology Reports
How To Read Your Laboratory Results
Your report will display your serum CA 72.4 concentration in units per millilitre (U/mL). In healthy adults, baseline levels are typically low (often < 6.9 U/mL, depending on the assay reference range). Mild elevations can occur in benign conditions such as peptic ulcer disease, pancreatitis, benign ovarian cysts, or liver cirrhosis. However, significantly elevated or progressively rising levels suggest an active tumour process in the stomach, ovaries, or colon. Your doctor will interpret this level in combination with endoscopic findings, imaging scans, and your clinical history.
Results Timeline: Your specialist diagnostic report is typically available within 7 days of your blood draw.
Medical Consultation
Need Help? Private GP Consultations
Tumour markers require experienced clinical evaluation within the wider context of your medical background. If your CA 72.4 result is elevated or demonstrates an upward trend, or if you are troubled by persistent gastric discomfort, unexplained weight loss, or pelvic symptoms, our private GP service is available on site. Our clinicians can interpret your results, arrange complementary investigations (such as CEA, CA 125, or ultrasound scans), and coordinate rapid referrals to gastroenterologists or oncologists.

Frequently Asked Questions
Do I need to fast before a CA 72.4 blood test?
No special fasting is strictly required before a CA 72.4 blood test. You may eat and drink normally prior to your appointment unless your doctor has scheduled additional blood tests alongside it that require fasting.
What conditions are associated with elevated CA 72.4 levels?
Elevated CA 72.4 levels are most strongly linked to gastric (stomach) adenocarcinoma and epithelial ovarian carcinomas (specifically mucinous ovarian tumours). It can also be elevated in other gastrointestinal malignancies, such as colorectal or oesophageal cancer, as well as certain benign gastrointestinal or ovarian disorders.
Can CA 72.4 be used for general cancer screening in healthy people?
No. Like most tumour markers, CA 72.4 is not recommended for routine population screening in asymptomatic individuals due to variable sensitivity in early stages. It is most clinically valuable when used to evaluate symptomatic patients, assist in differential diagnosis, and monitor known disease response to treatment.
How quickly will I receive my CA 72.4 test results?
Because this biomarker requires specialist quantitative analysis performed at an accredited referral laboratory, your comprehensive diagnostic report will be securely delivered within 7 days.
Is the phlebotomy fee included in the £80.00 price?
No, the £24.00 phlebotomy service fee is separate and covers the professional blood draw carried out by our qualified clinical practitioners at our central Victoria clinic.

Most Searched Online Questions About CA 72.4
Why is CA 72.4 combined with CEA in stomach cancer?
While Carcinoembryonic Antigen (CEA) is commonly used across digestive cancers, CA 72.4 offers superior diagnostic specificity for gastric adenocarcinoma. Combining CA 72.4 with CEA and CA 19.9 provides significantly higher sensitivity for detecting gastric malignancy and monitoring post-operative recurrence than any single marker alone.
How does CA 72.4 relate to mucinous ovarian tumours?
CA 125 is the standard marker for serous ovarian cancers, but it can be normal in mucinous ovarian neoplasms. CA 72.4 is frequently elevated in mucinous ovarian tumours, making it a valuable adjunct when investigating complex adnexal masses.
Can benign gastrointestinal conditions cause high CA 72.4?
Yes. Although CA 72.4 demonstrates high diagnostic specificity compared to some other markers, non-malignant conditions like gastritis, peptic ulcers, pancreatitis, and benign gastrointestinal polyps can occasionally cause slight to moderate elevations.
