Catecholamines, Fractionated, Urinary Free and Vanillylmandelic Acid (VMA), 24-Hour Urine

Laboratory: Labcorp
Test code: 286161
Specimen: Urine
Fasting: Not stated
Turnaround: 6 - 9 days

Laboratory assay overview

Collection is of greatest value for evaluation of hypertension if performed during a hypertensive episode. Test is used to evaluate hypertension, especially if paroxysmal and to evaluate orthostatic hypertension. Test is also useful in the diagnosis of pheochromocytoma and in the diagnosis and follow-up of neuroblastoma and ganglioneuroblastoma, retinoblastomas, carcinoid tumors, carotid body tumors, and stress. Preoperative evaluation of neoplasia of childhood, especially when the tumor is in or about the adrenals. Evaluate multiple endocrine adenomatosis. Evaluate patient with medullary carcinoma of thyroid (for coexistent pheochromocytoma).

Catecholamines, Fractionated, Urinary Free, 24-Hour Urine

Laboratory: Labcorp
Test code: 004176
Specimen: Urine
Fasting: Not stated
LOINC: 92938-0
Turnaround: 4 - 7 days

Laboratory assay overview

Work up neuroblastoma; diagnose pheochromocytoma. Pheochromocytomas and occasional paragangliomas may cause persistent or paroxysmal hypertension. Work up palpitation, severe headache, diaphoresis. Urine collections are preferred to blood sampling when there is suspicion for tumor (e.g., family history of MEA II) when hypertension is not paroxysmal. Evaluate for possible multiple endocrine adenomatosis type II.

Verify these ranges and sources

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
