Catecholamines (Adrenaline+Nor Adrenaline) – [Urine, 24 Hours]

Description

Twenty-four-hour urinary catecholamine measurement quantifies the total excretion of epinephrine and norepinephrine metabolites over a full day. This assay supports the diagnosis and monitoring of catecholamine-secreting tumors (pheochromocytoma/paraganglioma) and evaluates autonomic disorders.

Parameter Details
Analytes • Epinephrine (adrenaline)
• Norepinephrine (noradrenaline)
Specimen type Entire urine collected over 24 hours in preservative-containing container (e.g., acidified with HCl).
Collection requirements • Discard first morning void, then collect all urine for next 24 h, including the final void.
• Keep container refrigerated or on ice during collection.
• Record total volume accurately.
Assay methodology Liquid chromatography–tandem mass spectrometry (LC–MS/MS) or high-performance liquid chromatography (HPLC) with electrochemical detection.
Turn-around time 2–4 working days
Reference interval Method-specific; typical adult ranges:
• Epinephrine: 1–20 µg/24 h
• Norepinephrine: 15–80 µg/24 h

🔹Sample Transportation

Samples are to be transported in a triple package format:

Wrap the primary sample container (I.e respective sample bottle EDTA, SST …)

Place the primary container uprightly in a water-tight secondary container (the secondary container could be a Falcon tube or something similar)

Place the secondary container into an outer package (A sample biohazard bag), while ensuring this bag is well sealed to preserve sample integrity.

Note all samples are expected to come with indicating patient name, Sex, Age, Test Required.

Blood samples will be transported on cold chain.
