Test Overview & Methodology
The Homovanillic Acid (HVA) 24‑hour urine test quantifies the dopamine metabolite using high‑performance liquid chromatography with electrochemical detection (HPLC‑EC) – the gold‑standard method for detecting neuroblastoma and pheochromocytoma. This assay provides essential evidence for diagnosing catecholamine‑secreting neoplasms and guides both pediatric and adult oncologists in the UAE.

Physician Insight & Safety Protocols
“I understand that testing for catecholamine metabolites can feel overwhelming, particularly when cancer is a concern. This assay is a highly specific tool for neuroendocrine tumors, but it is not a stand‑alone diagnosis – it must be correlated with imaging and symptoms. Please never self‑interpret results; always review them with your oncologist or endocrinologist.” — Mr. Prabhakar Reddy Kalathoor, Specialist Diagnostic Radiology, DHA Registration ID: 61713011
Medication Advisory
Important Medication Warning
Do not discontinue prescribed medication without consulting your doctor. Abrupt changes can provoke a catecholamine crisis. Specifically, L‑Dopa must be stopped at least 72 hours before and during collection unless contraindicated by your physician – failure may cause false‑positive HVA results.
Exclusion Criteria & Emergency Red Flags
Who Should Not Collect Without Clearance
- Active urinary tract infection (signs: dysuria, hematuria).
- Severe renal impairment (eGFR <30 mL/min/1.73m²) unless cleared by nephrologist.
- Known hypersensitivity to hydrochloric acid (HCl) used as urine preservative.
- RED FLAGS: If during collection you develop sudden severe headache, pounding heartbeat, drenching sweats, or extreme high blood pressure, stop collection, lie flat, and call 998 immediately.
Patient FAQ & Clinical Guidance
1. Why do I need a 24‑hour urine test for HVA instead of a single blood draw?
A: The 24‑hour collection captures the full daily excretion pattern, eliminating episodic fluctuations that a single blood sample can miss, ensuring accurate tumor marker assessment.
2. I take L‑Dopa for a neurological condition. How does that affect the test?
A: L‑Dopa directly increases urinary HVA levels, causing false‑positive results; you must stop the medication at least 72 hours before and during collection unless contraindicated by your physician. Do not stop without medical guidance.
3. How quickly will I receive the results and can a doctor explain them to me?
A: Your verified report is ready by Friday/Tuesday, and a free telephonic clinical guidance session with a DHA‑licensed specialist is included to translate findings into actionable next steps.
4. How should I collect and store the 24‑hour urine sample?
A: Collect all urine over 24 hours. Transfer a 50 mL aliquot into the provided container, which already contains 50% HCl preservative (do not add extra). Keep refrigerated or on ice during collection and transport. Avoid L‑Dopa for 72 hours before and during collection. For questions, contact +971 54 548 8731.
