Cases of unusually severe or intermittent high blood pressure, especially before age 20.
A common malignant tumor in children derived from the neural crest.
Rare tumors outside the adrenal glands that secrete similar hormones. 2. Interpretation of Results Cases of unusually severe or intermittent high blood
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.
This guide outlines the clinical interpretation, collection procedures, and reference standards for urinary catecholamine testing, primarily used to diagnose neuroendocrine tumors. This guide outlines the clinical interpretation
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
Catecholamines Fractionated by LC-MS/MS, Urine Free - ARUP Lab or collection errors.
A typically benign adrenal gland tumor in adults that causes excessive hormone production.
