Catecholamines are chemicals made by nerve tissue (including the brain) and the adrenal gland.
The main types of catecholamines are dopamine, norepinephrine, and epinephrine. These chemicals break down into other components, which leave your body through your urine.
A urine test can be done to measure the amount of catecholamines produced by your body. Separate urine tests may be done to measure related substances.
Catecholamines can also be measured with a blood test.
For this test, you must collect your urine in a special bag or container every time you urinate for a 24-hour period.
For an infant, thoroughly wash the area where urine exits the body.
This procedure may take a few tries. An active baby can move the bag causing urine to go into the diaper.
Check the infant often and change the bag after the infant has urinated into it. Drain the urine from the bag into the container provided by your health care provider.
Deliver the sample to the laboratory or to your provider as soon as possible.
Stress and heavy exercise may affect the test results.
Some foods can increase catecholamines in your urine. You may need to avoid the following foods and beverages for several days before the test:
Many medicines can interfere with test results.
The test involves only normal urination, and there is no discomfort.
The test is usually done to diagnose an adrenal gland tumor called pheochromocytoma. It may also be used to diagnose neuroblastoma. Urine catecholamine levels are increased in most people with neuroblastoma.
The urine test for catecholamines may also be used to monitor those who are receiving treatment for these conditions.
All of the catecholamines are broken down into inactive substances that appear in the urine:
The following normal values are the amount of the substance found in the urine over a 24-hour period:
Normal value ranges may vary slightly among different laboratories. Talk to your provider about the meaning of your specific test results.
The examples above show the common measurements for results for these tests. Some laboratories use different measurements or may test different specimens.
Elevated levels of urinary catecholamines may indicate:
The test may also be performed for:
There are no risks.
Several foods and drugs, as well as physical activity and stress, can affect the accuracy of this test.
