What Is a Catecholamines, 24 Hours Urine Test?
The catecholamines 24 hour urine test measures the levels of stress hormones produced by the adrenal glands in a urine sample collected over a full day. The three hormones measured are epinephrine (adrenalin), norepinephrine (noradrenalin), and dopamine.
This urinary catecholamines test is typically ordered when a doctor suspects a hormone-producing tumour or a disorder affecting the body's automatic functions. The sample used is urine collected over 24 hours, which gives a more complete picture than a single spot sample.
What Does a Catecholamines, 24 Hours Urine Test Measure?
The urine catecholamines test looks at three hormones in your urine that your adrenal glands release, especially during stress. Here is what each one does:
| Parameter | What It Does |
|---|---|
| Epinephrine (Adrenalin) | Raises heart rate and blood pressure, boosts energy, and heightens the body's response to stress |
| Norepinephrine (Noradrenalin) | Narrows blood vessels, increases heart rate, and carries signals between nerve cells in the brain |
| Dopamine | Helps regulate blood vessel tone, heart function, intestinal muscle activity, and glucose metabolism |
Why Is a Catecholamines, 24 Hours Urine Test Done?
Doctors order this test to investigate unusual symptoms that may point to a hormone imbalance or a specific type of tumour. It is also used to track how well treatment is working in certain conditions.
Common Symptoms That May Require This Test
Your doctor may recommend a 24 hour urinary catecholamines test if you are experiencing any of the following:
- High blood pressure that is difficult to control
- Frequent, severe headaches
- Excessive sweating without a clear cause
- Heart palpitations or irregular heartbeats
- Tingling sensations in the arms or legs
- Unexplained weight loss
- Persistent feelings of anxiety or trembling
Conditions This Test Can Help Detect
The urinary catecholamines (24 hours) test can help identify a range of conditions, including:
- Pheochromocytoma, a rare tumour of the adrenal glands that causes excess hormone production
- Neuroblastoma, a tumour arising from nerve tissue that mainly affects infants and young children
- Paraganglioma, a tumour that forms near the adrenal glands and can cause elevated blood pressure
- Ganglioneuroblastoma and ganglioneuroma, which are related nerve tissue tumours
- Autonomic dysfunction and autonomic neuropathies, where the body's involuntary functions do not work as they should
Catecholamines, 24 Hours Urine Test for Chronic Disease Monitoring
This test is also used to check how well treatment is progressing in patients already diagnosed with conditions such as pheochromocytoma or neuroblastoma. Urinary catecholamines are recognised biomarkers for tracking treatment response and predicting outcomes in neuroblastoma.
Doctors may repeat the 24 hour urine catecholamines test periodically, typically every few months during active treatment, to assess whether hormone levels are returning to normal.
How to Prepare and What to Expect
Collecting a 24-hour urine sample is straightforward, but a little preparation goes a long way in making sure your results are accurate.
Do You Need to Fast?
No, fasting is not required for this test. However, certain foods and drinks must be avoided for 2 to 3 days before and during the collection period, as they can interfere with results.
Practical Tips Before Your Test
Following these steps will help ensure a reliable result:
- Avoid tea, coffee, bananas, citrus fruits, chocolate, vanilla, walnuts, fava beans, avocados, cocoa, and liquorice for 2 to 3 days before the test
- Steer clear of strenuous exercise, tobacco use, and unnecessary stress in the days leading up to collection
- Tell your doctor about all medications you are taking, especially antidepressants and blood pressure medicines, as these can affect catecholamine levels
- Keep the collection container refrigerated throughout the 24-hour period; a preservative is usually provided with the container
Step-by-Step Procedure
The collection process is simple and takes place at home. Follow these steps carefully:
- On the morning of day one, urinate into the toilet as usual and do not collect this sample. Note the exact time.
- From this point on, collect every urine sample throughout the day and night into the provided container.
- Keep the container in a refrigerator between collections.
- On the morning of day two, collect your first urine of the morning into the container, noting the exact time this 24-hour period ends.
- Seal the container securely and arrange for it to be transported to the laboratory promptly.
Factors That Can Affect Accuracy
Several factors can alter catecholamine levels in urine and affect the reliability of your results:
- Physical or emotional stress during the collection period
- Caffeinated drinks, alcohol, or tobacco use
- Certain foods listed in the preparation tips above
- Specific medications, including antidepressants and some blood pressure drugs
- An illness such as a heart attack, stroke, or sleep apnoea during the collection period
Understanding Your Catecholamines, 24 Hours Urine Test Results
Your results show the total amount of each hormone excreted in urine over 24 hours. A doctor will compare these values against reference ranges and consider your full medical history before drawing any conclusions.
| Parameter | Reference Range | Unit |
|---|---|---|
| Dopamine | 65 to 400 | mcg/24 hours |
| Epinephrine (Adrenalin) | 0.5 to 20 | mcg/24 hours |
| Norepinephrine (Noradrenalin) | 15 to 80 | mcg/24 hours |
| Metanephrine | 24 to 96 | mcg/24 hours |
| Normetanephrine | 75 to 375 | mcg/24 hours |
| Total Urine Catecholamines | 14 to 110 | mcg/24 hours |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can cause catecholamine levels to appear higher or lower than expected, even without an underlying tumour. Your doctor will take these into account:
- Tricyclic antidepressants are among the medicines that most commonly interfere with this test. Ideally, these should be stopped at least two weeks before the test, but only under medical supervision.
- Physical illness, such as a heart attack, stroke, or obstructive sleep apnoea, can raise catecholamine levels independently of any tumour.
- Having a menstrual period on the day of collection may also influence results.
- The test should not be performed on patients withdrawing from substances known to cause a rebound rise in catecholamine levels.
How to Maintain Healthy Levels
These general wellness habits support balanced hormone levels over time:
- Practise regular stress management through adequate sleep, mindfulness, or relaxation techniques
- Limit caffeine, alcohol, and tobacco consumption in everyday life
- Stay physically active, but avoid intense exercise immediately before or during a collection period

Frequently Asked Questions
Catecholamine levels shift throughout the day depending on activity, stress, and other factors. A single sample taken at one point in time may not reflect your body's overall hormone output. Collecting urine over a full 24 hours gives a far more accurate and representative picture of how much of these hormones you are producing.
The physical act of having blood drawn can itself trigger a stress response, which temporarily raises catecholamine levels in the blood. This makes blood results less reliable. A 24 hour urinary catecholamines test avoids this issue, since the collection happens in the normal course of daily life without any physical stress caused by the test itself.
For 2 to 3 days before and during the collection period, avoid bananas, citrus fruits, chocolate, coffee, tea, vanilla, walnuts, fava beans, avocados, cocoa, caffeinated colas, and liquorice. These foods contain compounds that can artificially raise catecholamine readings and lead to misleading results.
Yes, a number of medicines, particularly antidepressants and blood pressure medications, can affect catecholamine urine test results. Always inform your doctor about every medicine, supplement, or herbal product you are taking before the test. Never stop any prescribed medication without your doctor's guidance.
Elevated catecholamine levels in a catecholamine assay, urine often point to the presence of a hormone-secreting tumour such as a pheochromocytoma. Your doctor will likely arrange further tests, including imaging, to locate the source if levels are significantly raised. A high result on its own is not a diagnosis; your doctor will assess it alongside your symptoms and medical history.
The collection involves only normal urination and carries no risks or discomfort. There are no needles, no injections, and no invasive steps involved. The main requirement is careful attention to collecting every urine sample during the 24-hour window and keeping the container properly refrigerated.
If your urine catecholamine test results are outside the normal range, your referring doctor will usually direct you to an endocrinologist. An endocrinologist specialises in hormone-related conditions and can guide the next steps for investigation and management.
