Test Overview & Methodology
The Serotonin (5‑HT) 24‑Hour Urine Test quantifies total serotonin excretion using LC‑MS/MS to aid in the diagnosis of carcinoid syndrome and neuroendocrine tumours. This definitive neuroendocrine marker test is recommended by DHA clinical guidelines for patients presenting with flushing, wheezing, and diarrhoea.

Physician Insight & Safety Protocols
“This LC‑MS/MS urinary serotonin test is the most reliable non‑invasive tool for detecting carcinoid tumours. However, a single elevated result must be correlated with 5‑HIAA and clinical imaging to avoid false‑positive stress artefacts. Always discuss your symptoms and medication history with your endocrinologist before testing.” – Mr. Prabhakar Reddy Kalathoor, Specialist Diagnostic Radiology, DHA License 61713011

Patient FAQ & Clinical Guidance
1. Why do I need to avoid certain foods before the serotonin urine test?
Avoiding bananas, walnuts, tomatoes, and specific fruits for 48 hours prevents dietary serotonin from falsely elevating your urinary serotonin result by LC‑MS/MS. Even trace amines in these foods can mimic 5‑HT and obscure a true carcinoid diagnosis.
2. Can I collect the sample at home?
Yes, our temperature‑controlled cold‑chain home collection service is available daily from 8 AM to 11 PM. A trained phlebotomist will deliver the collection container and provide detailed instructions for the 24‑hour urine collection. Alternatively, you may visit our DHCC facility for supervised collection.
3. How quickly will I receive my serotonin hormone urine report and can a doctor explain it?
Your LC‑MS/MS serotonin 24‑hour urine report is ready within 2 working days after the Saturday/Wednesday collection slot. The report includes a free tele‑consultation for clinical interpretation. DHA‑licensed specialists will review the quantitative levels and guide you on the next steps.
