CA 72-4
CA 72-4 is a glycoprotein marker associated with gastric and ovarian tissue. For women, this marker can be relevant because elevated levels are sometimes seen with ovarian cysts and other benign gynaecological conditions.

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.
What It 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.
Why It 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.
When to Test
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.

Lifestyle Tips
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.
