Ovarian Tumour Marker Blood Test
Measures the markers of ovarian tumour
What is this test?
The CA-125 blood test is a diagnostic tool used to measure the levels of a protein called cancer antigen 125 (CA-125) in the bloodstream. CA-125 is primarily produced by cells lining the ovaries and can be elevated in certain conditions, particularly ovarian cancer.
It can serve multiple purposes, such as:
- Diagnosis: Elevated levels of CA-125 may indicate the presence of ovarian cancer, especially in postmenopausal women. However, it is important to note that CA-125 can also be elevated in non-cancerous conditions, such as endometriosis, pelvic inflammatory disease, and even during menstruation.
- Monitoring: CA-125 levels can be monitored over time to track the progression or response to treatment of ovarian cancer.
It's important to understand that the CA-125 blood test is not definitive for diagnosing ovarian cancer, and further evaluation, such as imaging studies or biopsies, may be required.
Here are some symptoms that you might consider an ovarian tumour marker (CA-125) blood test:
- Persistent abdominal pain or discomfort
- Bloating or feeling of fullness
- Pelvic pain or pressure
- Changes in urinary habits, such as increased frequency or urgency
- Changes in bowel habits, including constipation or diarrhoea
- Loss of appetite or unintentional weight loss
- Abnormal vaginal bleeding or postmenopausal bleeding
How long does it take?
The test turnaround is 24 hours.

The benefits of this blood test
- Check CA-125 ovarian tumour marker
- Get support and advice from our doctors
A CA-125 blood test may be recommended if a woman shows persistent symptoms of ovarian cancer such as abdominal pain, bloating, or changes in urinary or bowel habits.
Monitoring Ovarian Cancer Treatment
Regular CA-125 blood tests are recommended for ovarian cancer patients to monitor their response to treatment. These tests help healthcare providers track changes in CA-125 levels over time, which can assist in evaluating the effectiveness of therapies and determining the need for adjustments.
Surveillance for Ovarian Cancer Recurrence
After initial ovarian cancer treatment, regular CA-125 blood tests may be recommended as part of a surveillance plan to detect any potential disease recurrence. Rising CA-125 levels can indicate recurrent ovarian cancer early, prompting further investigation.
Assessing Pelvic Masses or Abnormalities
If a doctor detects a mass or abnormality in the pelvic area during a physical exam or through imaging tests, they may order a CA-125 blood test. This test is used to help determine the likelihood that ovarian cancer is present. The results can help the doctor decide if further diagnostic tests or referrals to a specialist are necessary.
