What are tumour markers, and what can they tell you?

Tumour markers are measurable substances associated with particular cancers. Blood testing provides useful information for investigating selected clinical findings, assessing treatment response and identifying changes that need further evaluation. At Kauri, choose an individual marker or a male or female profile, with results interpreted in the context of your health and the reason for testing.

The benefit is a clearer, clinically informed next step. Your clinician brings together your marker results, symptoms, medical history and relevant investigations to explain what the findings mean and whether further assessment or follow-up is needed.

Book this tumour-marker profile

Each profile brings selected markers together at one package price. Your clinician can help match a profile or individual tests to your medical history and the question being assessed. These are targeted clinical tests, rather than routine cancer screening for people without symptoms.

What does each tumour marker tell you?

Alpha-fetoprotein (AFP)

Tumour marker for liver cancer

AFP is an established blood marker associated with liver cancer and certain germ-cell tumours. Used alongside liver imaging, it helps clinicians investigate suspected disease and assess response to treatment. In selected people with chronic hepatitis or cirrhosis, AFP can form part of a liver-cancer surveillance plan with ultrasound. Your liver history and previous results help give the measurement its clinical meaning.

Cancer antigen 125 (CA-125)

Tumour marker for ovarian cancer

CA-125 is a tumour marker associated with ovarian cancer. When an ovarian abnormality needs investigation, it adds useful information alongside symptoms and ultrasound findings. It also helps the treating specialist evaluate treatment response and check for changes after treatment. Your menstrual cycle and conditions such as endometriosis are considered when interpreting the result.

Cancer antigen 15-3 (CA 15-3)

Tumour marker for breast cancer

CA 15-3 is a tumour marker associated with breast cancer. Its established value is in assessing changes during treatment and follow-up, especially in advanced breast cancer. Comparing results over time, together with imaging and symptoms, helps the specialist understand treatment response and decide when further investigation is useful. It can be relevant to both women and men receiving breast-cancer care.

Carbohydrate antigen 19-9 (CA 19-9)

Tumour marker for pancreatic and selected gastrointestinal cancers

CA 19-9 is a tumour marker associated with pancreatic, bile-duct and selected gastrointestinal cancers. Its strongest clinical role is helping assess disease activity and treatment response in people with an established diagnosis. Comparing blood results with scans gives the treating specialist useful information for ongoing care. The clinician also considers bile-duct blockage and inflammation when explaining a raised result.

Carcinoembryonic antigen (CEA)

Tumour marker for colon and rectal cancer

CEA is a tumour marker associated with colon and rectal cancer. It has an established role in assessing treatment response and checking for changes after treatment that may need investigation. A series of results helps the specialist understand the pattern over time and plan follow-up. Smoking history and other health conditions are part of interpreting the number accurately.

Free PSA

Marker used in prostate cancer assessment

Free PSA adds detail to prostate cancer risk assessment by measuring the PSA that circulates without being attached to blood proteins. Its relationship to the other PSA measurements on the report helps clinicians assess whether further prostate investigation is appropriate. Age, symptoms and prostate history complete the assessment and guide the next step.

Neuron-specific enolase (NSE)

Tumour marker for small-cell lung cancer

NSE is a tumour marker associated particularly with small-cell lung cancer and certain neuroendocrine tumours, including neuroblastoma. It provides supporting evidence during a specialist assessment and helps evaluate how the disease responds to treatment. Looking at NSE together with scans and other findings gives the treating team a more informed picture of these specific conditions.

When can tumour-marker testing be useful?

Your doctor has requested a specific marker to help investigate a clinical finding.
You need to follow a previously raised result or compare measurements over time.
You have an established monitoring plan from your treating cancer specialist.

If your starting point is a symptom or family history rather than a test request, begin with a medical assessment. The right next step may be a targeted marker, imaging or an established screening test. Bring previous reports so the assessment builds on what is already known.

Preparing for your tumour-marker blood test

Most of these blood tests do not usually require fasting on their own. Preparation can change if you book other tests at the same visit. Bring your test request and previous reports, and tell us about medicines, supplements, pregnancy, your menstrual cycle and any recent illness or prostate procedures. Do not stop prescribed medicines yourself. The team confirms preparation and result timing for the tests you book.

From your result to a clear next step

Your clinician reviews the laboratory range, previous measurements and relevant symptoms. If a value is raised, the next step may be repeat testing, imaging or specialist assessment. For monitoring, trends are often more informative than one isolated number; using the same laboratory method helps comparison. Bring your specialist's plan so follow-up testing stays aligned with your care.

Patient questions

Tumour-marker testing: your questions answered

Can a tumour-marker blood test detect cancer?

Certain markers help investigate suspected cancer, while others are most useful for assessing treatment response or changes after treatment. Their benefit is the additional information they bring to a focused clinical assessment. Confirming or excluding cancer requires the overall findings—often imaging and sometimes a biopsy—rather than a blood result alone.

Does a high tumour marker always mean cancer?

No. Inflammation, benign conditions and other factors can raise some markers. The cause depends on which marker is raised, how much it has changed and the clinical picture. Review the result with a clinician rather than interpreting the laboratory flag on its own.

What is included in the male and female profiles?

The male profile contains AFP, CEA, CA 19-9, Free PSA and NSE. The female profile contains AFP, CEA, CA 19-9, CA-125, CA 15-3 and NSE. Individual tests are also available. The groupings are convenient ordering options; suitability depends on your clinical needs.

How much do tumour-marker tests and profiles cost?

AFP is 400 baht; CEA is 450 baht; CA-125, CA 15-3 and CA 19-9 are 900 baht each; Free PSA is 990 baht; and NSE is 1,500 baht. When booked together as a package, the male profile is 3,900 baht for all five tests and the female profile is 4,500 baht for all six tests. NSE is included in both profiles.

Which lung cancer is NSE associated with?

NSE is associated particularly with small-cell lung cancer. Specialists use it with other findings to support assessment and evaluate treatment response. It also has a role in selected neuroendocrine tumours. For lung-cancer screening, the appropriate approach is based on age, smoking history and imaging eligibility; NSE has a different, more specific purpose.

How do tumour markers fit alongside cancer screening?

Tumour markers answer specific clinical questions about suspected or known disease. Routine screening looks for cancer before symptoms, using tests chosen for your age and risk—such as mammography, cervical screening or stool testing and colonoscopy. CA-125 is not recommended for routine ovarian-cancer screening in healthy, average-risk women. A clinician helps you choose the right combination rather than treating these tests as interchangeable.

Do I need to fast, and when will I receive results?

These markers usually do not require fasting when ordered alone. Other tests booked together may have different instructions. Kauri confirms preparation and the expected turnaround for your selected tests before collection; result times are not the same for every marker.

Can I bring a test request or results from another doctor?

Yes. Bring the requested marker names, previous results and any follow-up instructions. Tell us which laboratory performed earlier testing, because methods and reference ranges can differ. If you are receiving cancer treatment, follow-up should remain coordinated with your treating specialist.
