Test Overview & Methodology
The Serotonin (5-HT) Serum Test quantifies circulating serotonin levels using high-performance liquid chromatography with electrochemical detection (HPLC-EC) to aid in the diagnosis and monitoring of carcinoid tumors and serotonin syndrome. This test is essential for oncological workups where neuroendocrine tumor secretion is suspected, providing accurate, actionable data under strict UAE pre-analytical conditions.
| Feature | Our Serotonin (5-HT) Test | Closest Alternative (RIA/ELISA) |
|---|---|---|
| Precision (CV%) | ≤ 5% (HPLC-EC, gold standard) | 8-15% (cross-reactivity) |
| Methodology | HPLC-EC (direct specific detection) | Immunoassay (potential interference) |
| Turnaround Time | Sample by 9 AM (Tue), Report by (Fri) | 5-7 working days |
Physician Insight & Safety Protocols
“As a DHA-licensed specialist in diagnostic radiology, I emphasize that serotonin results must be correlated with clinical signs and advanced imaging; an isolated elevation does not confirm malignancy. False-positives may occur with diet or medication non-compliance, and false-negatives in intermittent secreting tumors. Always interpret alongside 5-HIAA and chromogranin A for a comprehensive neuroendocrine tumor workup.”
— Mr. Prabhakar Reddy Kalathoor, Specialist Diagnostic Radiology, DHA ID: 61713011
Medication & Safety Advisory
Critical Warning: Do not discontinue prescribed medication without consulting your doctor. Abrupt cessation of MAO inhibitors, lithium, or SSRIs can precipitate severe withdrawal or serotonin syndrome.
- Exclusion Criteria: Failure to adhere to 48-hour dietary and medication restrictions; known hemolyzed or improperly chilled specimen; prior anaphylaxis to phlebotomy.
- Pre-test Restrictions: Strictly avoid bananas, walnuts, tomatoes, pineapples, plums, gooseberries, avocados, aubergines, kiwi fruits, chocolates, and drugs like Lithium, MAO Inhibitors, Methyldopa, Reserpine, Fluoxetine; no strenuous exercise 48 hours before and during collection.
- Sample Requirements: 3 mL (2 mL min.) serum from 1 SST; ship refrigerated or frozen.
- ER Red Flags: If you experience sudden high fever, muscle rigidity, agitation, rapid heart rate, severe flushing, wheezing, or hypotension, proceed directly to the emergency department — these may indicate serotonin syndrome or carcinoid crisis.
Patient FAQ & Clinical Guidance
1. Why is the Serotonin Serum Test used in cancer care?
This test detects elevated serotonin from neuroendocrine tumors, especially carcinoid, guiding diagnosis and monitoring of serotonin-secreting malignancies. Clinicians order it alongside 5-HIAA and chromogranin A when patients present with flushing, diarrhea, wheezing, or cardiac valve lesions suggestive of carcinoid syndrome. Serial measurements can track treatment response.
2. How should I prepare for the Serotonin Serum test?
You must strictly avoid specific foods and medications for 48 hours before sample collection to prevent false results. Refrain from bananas, walnuts, tomatoes, pineapples, plums, gooseberries, avocados, aubergines, kiwi, chocolates, and drugs such as lithium, MAO inhibitors, methyldopa, reserpine, fluoxetine. No strenuous exercise. Continue other prescribed medicines unless directed otherwise by your doctor.
3. What do the results mean, and what is the normal range?
Elevated serotonin levels may indicate a carcinoid tumor, but results must be interpreted alongside other markers and clinical findings. Typical reference intervals vary between labs; our validated adult range is 50–200 ng/mL (HPLC-EC). Values significantly above this warrant further investigation for neuroendocrine tumor. Low levels are clinically non-specific. Your doctor will discuss the full interpretation.
