What is the purpose of this test?
The Catecholamines without Creatinine Urine Test, Fractionated and VMA, 24-Hour measures specific chemicals in your urine that play important roles in regulating stress responses and maintaining balance in your body. Catecholamines, which include norepinephrine, epinephrine, and dopamine, are hormones produced by the adrenal glands and the nervous system. These hormones help control blood pressure, heart rate, and the body's response to stress. By assessing their levels, the test can detect imbalances that may indicate health issues.
This test also measures vanillylmandelic acid (VMA), a breakdown product of catecholamines, which provides additional insight into how the body processes these hormones. Abnormal levels of catecholamines or VMA can indicate conditions such as pheochromocytoma (a rare adrenal gland tumor), neuroblastoma, or stress-related disorders. This test can help doctors diagnose these conditions and monitor their progression or treatment.
Who should get this test?
This test may benefit:
- Individuals with high blood pressure that is difficult to control.
- Those experiencing symptoms like rapid heartbeat, severe headaches, or excessive sweating.
- Patients with a family history of adrenal or neuroendocrine tumors.
- Individuals being monitored for known adrenal gland disorders or neuroblastoma.
- People with unexplained anxiety, palpitations, or stress-related symptoms.
