This guide outlines the clinical interpretation, collection procedures, and reference standards for urinary catecholamine testing, primarily used to diagnose neuroendocrine tumors.
A common malignant tumor in children derived from the neural crest. This guide outlines the clinical interpretation
Interpretation relies on comparing 24-hour excretion levels against established reference ranges. This guide outlines the clinical interpretation
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
The measurement of urinary catecholamines (epinephrine, norepinephrine, and dopamine) is essential for diagnosing and monitoring several conditions:
