A typically benign adrenal gland tumor in adults that causes excessive hormone production.
Catecholamines Fractionated by LC-MS/MS, Urine Free - ARUP Lab
Interpretation relies on comparing 24-hour excretion levels against established reference ranges. A typically benign adrenal gland tumor in adults
Rare tumors outside the adrenal glands that secrete similar hormones. 2. Interpretation of Results
The measurement of urinary catecholamines (epinephrine, norepinephrine, and dopamine) is essential for diagnosing and monitoring several conditions: Primarily used as a marker for neuroblastoma in
A result three times higher than the upper reference limit strongly indicates a neuroendocrine tumor. Minor increases (less than double) may stem from stress, drugs, or collection errors.
Primarily used as a marker for neuroblastoma in children, often analyzed alongside VMA and HVA. Adult Reference Ranges (Approximate): Epinephrine: < 18.3 µg/24h or < 30 µg/24h Norepinephrine: < 84.6 µg/24h or < 60 µg/24h Dopamine: < 459.6 µg/24h or < 600 µg/24h 3. 24-Hour Collection Protocol primarily used to diagnose neuroendocrine tumors.
This guide outlines the clinical interpretation, collection procedures, and reference standards for urinary catecholamine testing, primarily used to diagnose neuroendocrine tumors.
