CA 72-4 Tumor Marker

CA 72-4 is a gastric marker that can be measured as part of a preventive health assessment to help establish a personal baseline.

Doctor's Assessment Included

Reference Ranges

No established reference range

There is no Dutch reference value for CA 72-4. No Dutch guideline or laboratory handbook publishes one, and — unlike most blood values — no international standard exists for this test. Different analysers therefore report different numbers for the same person; the manufacturer itself requires that a CA 72-4 result only be read alongside the method used to measure it. Our laboratory sends samples to several partner laboratories, each with its own analyser and its own reference values. Your own result therefore arrives with the reference interval of the laboratory that examined your blood: that is the interval that applies to you. Discuss your result with your doctor.

Unit: ku/l

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

CA 72-4: what this test measures

CA 72-4 measures the blood concentration of a high-molecular-weight glycoprotein (TAG-72) expressed on the surface of certain gastrointestinal and reproductive cells. The marker is not specific to any single condition.

CA 72-4: why this value matters

CA 72-4 is sometimes used alongside other markers to monitor gastrointestinal or ovarian conditions. Because it is rarely elevated in healthy individuals, a raised result may prompt further investigation, though benign causes must always be considered.

CA 72-4: when is testing worthwhile?

CA 72-4 is typically ordered by a healthcare provider as part of a clinical evaluation. Consult your healthcare provider before arranging this test independently.

CA 72-4: symptoms of a high or low value

Low Levels

Low CA 72-4 levels are within the normal reference range and are not associated with specific symptoms.

High Levels

An elevated CA 72-4 may be investigated further, particularly when accompanied by gastrointestinal symptoms such as persistent nausea, abdominal discomfort, or unintentional weight changes.

CA 72-4: lifestyle and this value

Supporting your digestive health through a varied, plant-rich diet, reducing processed food consumption, maintaining a healthy weight, and avoiding tobacco contributes to overall gastrointestinal wellbeing. Consult your healthcare provider for personalised advice.

CA 72-4: frequently asked questions

Is CA 72-4 specific to cancer?
No. CA 72-4 can be elevated due to benign causes such as gastric inflammation, pancreatitis, or liver conditions. It cannot confirm or exclude any specific diagnosis.
Can CA 72-4 be used on its own to screen for stomach cancer?
No. Its clinical value comes from being used alongside other markers and diagnostic methods under healthcare provider guidance.
Do I need to fast before a CA 72-4 blood test?
Preparation may vary. Follow the guidance provided by your testing service or healthcare provider.
