At Diagnopein, we use advanced testing technology to ensure highly precise, accurate, and reliable results for detecting adrenal or nervous system disorders.
The 24-hour urine VMA test (Vanillylmandelic Acid Test) measures the amount of vanillylmandelic acid (VMA) in your urine collected over 24 hours. VMA is a waste product produced when the body breaks down catecholamines — hormones such as epinephrine (adrenaline) and norepinephrine (noradrenaline) released by the adrenal glands.
This test is crucial in diagnosing certain rare conditions like pheochromocytoma and neuroblastoma, which cause excessive production of these hormones. Elevated VMA levels in the urine can indicate an overactive adrenal gland or tumors affecting the sympathetic nervous system.
Why is the 24-Hour Urine VMA Test Important?
The 24-hour urine VMA test plays a key role in identifying hormone-secreting tumors and related disorders. Adrenal glands regulate stress responses and maintain metabolic balance, but when they produce too many hormones, symptoms can become severe and life-threatening if not detected early.
Frequent headaches, palpitations, or excessive sweating
High blood pressure that is difficult to control
Rapid heart rate or tremors
Anxiety or panic-like episodes without clear reason
Symptoms of pheochromocytoma or neuroblastoma
By measuring VMA levels, doctors can evaluate if your body is producing excessive catecholamines, helping diagnose adrenal gland tumors early and monitor treatment outcomes effectively.
Benefits of the 24-Hour Urine VMA Test
The test offers several benefits for accurate and early diagnosis of hormonal disorders.
Early Detection of Adrenal Tumors: Helps identify pheochromocytoma or neuroblastoma before symptoms worsen.
Non-invasive and Reliable: Requires only urine collection, avoiding complex procedures.
Helps Monitor Treatment: Assists in evaluating tumor response after surgery or medication.
Guides Hormone Regulation Therapy: Ensures the right medical management based on hormone activity levels.
Performing this test at Diagnopein ensures detailed insight into your body’s hormone metabolism and adrenal health.
How is the 24-Hour Urine VMA Test Done?
The procedure involves collecting all urine over a 24-hour period. Proper collection is important for accurate results.
Start the collection in the morning. Discard the first urine sample.
Collect all urine for the next 24 hours in a sterile container provided by Diagnopein.
Store the sample in a cool place or refrigerator throughout the 24-hour period.
Return the full collection to the laboratory once the period is complete.
Parameters and Normal Range
The test primarily measures the amount of vanillylmandelic acid (VMA) excreted in 24 hours.
Normal Range: 2 to 7 mg/24 hours (may vary slightly by lab method and diet).
High VMA levels may indicate conditions such as pheochromocytoma, neuroblastoma, or paraganglioma.
Low VMA levels are usually considered normal but may occur in certain metabolic conditions or medication use.
Your doctor will interpret the results in combination with clinical symptoms and other diagnostic findings.

Whether your doctor recommends this test for adrenal health evaluation or tumor detection, Diagnopeinensures you receive accurate reports and compassionate care.
The test involves collecting all urine over a 24-hour period. The urine is then analyzed in a laboratory to measure the levels of VMA. Your doctor will provide instructions on how to collect and store the urine sample properly.
At Diagnopein, we strive for quick turnaround times. Typically, you can expect the results of your 24 HRS URINE VMA test within a few days.
The test is used to detect conditions that lead to abnormal production of catecholamines, such as pheochromocytoma, neuroblastoma, and other adrenal gland-related tumors.
The 24 HRS URINE VMA test measures the amount of Vanillylmandelic Acid (VMA) in the urine, a metabolite of catecholamines. High levels of VMA can indicate the presence of tumors such as pheochromocytoma or neuroblastoma.
