Catecholamines, Fractionated, Random UrineUrine
Performed by: Quest Diagnostics
Catecholamines, Fractionated, Random Urine is a test that measures the levels of certain hormones called catecholamines in a random urine sample. Catecholamines are a group of hormones and neurotransmitters that include substances like epinephrine (adrenaline), norepinephrine, and dopamine. These chemicals play essential roles in the body's "fight or flight" response, regulating blood pressure, heart rate, and other physiological responses to stress.
The test is typically used to diagnose and monitor certain medical conditions, such as:
Pheochromocytoma: This is a rare tumor that can develop in the adrenal glands (located on top of the kidneys) and can produce excessive amounts of catecholamines. Elevated levels of catecholamines in urine can be a sign of pheochromocytoma.
Paraganglioma: Similar to pheochromocytoma, paragangliomas are rare tumors that can develop in other parts of the body and also produce excess catecholamines.
Neuroblastoma: This is a type of cancer that commonly occurs in children and can also produce high levels of catecholamines.
A random urine sample is collected for this test, which means that it can be taken at any time during the day without any specific preparation. The levels of catecholamines in the urine are measured to determine if they fall within the normal range or if there is an excess, which may suggest an underlying medical condition.
It's important to note that the interpretation of catecholamine levels in urine can be influenced by various factors, including:
- and stress.
Therefore, healthcare providers may consider additional tests and clinical information when making a diagnosis. If your healthcare provider has recommended this test, they will provide specific instructions on how to collect the urine sample and any other necessary preparations.
