What Is The CA 125 Test For?

CA 125 is a tumour marker sometimes raised in ovarian cancer and several benign conditions.

Conditions linked to CA 125

Ovarian cancer

Ovarian cancer

Ovarian cancer can be difficult to detect early because its symptoms are often subtle and easily attributed to other conditions.

How To Test CA 125

By buying a laboratory test kit with professional nurse or clinic collection, you can accurately measure CA 125 for total reassurance.

Professional analysis in an accredited laboratory ensures rapid result delivery.

Tests which include a CA 125 test:

What if CA 125 Results Are High?

Raised CA 125 can be seen in ovarian cancer, but it can also occur with benign (non-cancerous) conditions.

This result is sometimes treated as clinically significant, and it may be reviewed further to clarify the cause.

What if CA 125 Results Are Low?

CA 125 within the normal range is often considered reassuring.

A normal result does not fully rule out underlying causes of ongoing symptoms, and persistent symptoms can still be associated with conditions that may be assessed further.

Why Take The CA 125 Test?

This test supports assessment of ovarian symptoms and monitoring in women with a history of ovarian disease. It is not diagnostic alone but helps guide the need for imaging or specialist review. It is most useful when combined with symptoms and clinical judgement.

Who Should Take This Test?

This Test is advised if you:
