Test Overview & Methodology
The Secretin Stimulation Test for Gastrin is a gold‑standard provocative neuroendocrine assay that measures serial serum gastrin levels after intravenous secretin challenge, definitively separating gastrinoma (Zollinger‑Ellison syndrome) from pseudo‑hypergastrinemia.
| Feature | Our Test (1800 AED) | Basal Gastrin Alone |
|---|---|---|
| Method | Chemiluminescent Immunoassay (CLIA) on 6 timed specimens | Single basal CLIA measurement |
| Provocation | Secretin 2 U/kg IV bolus, serial draws at 0, 5, 10, 15, 20, 25, 30 min | None |
| Sensitivity for Gastrinoma | >95% | 50–60% |
| Turnaround | Same‑day reporting after Monday/Thursday morning collection | 2–3 days |
Physician Insight & Safety Protocols
“While this dynamic test provides unparalleled sensitivity in ruling in a gastrinoma, it must be correlated with high‑resolution imaging (EUS, multiphase CT, 68Ga‑DOTATATE PET) and gastric acid studies. Always interpret a positive result—especially a classical rise of >200 pg/mL above baseline—in the context of your patient’s clinical presentation and medication history.”
— Mr. Prabhakar Reddy Kalathoor, Specialist Diagnostic Radiology, DHA Registration ID: 61713011
⚠ Advisory: Medication & Safety
Do not discontinue prescribed medications, particularly proton pump inhibitors or H2 blockers, without explicit consultation with your treating physician, as abrupt withdrawal may precipitate dangerous gastric acid rebound.
⛔ Exclusion Criteria & Emergency Red Flags
- Absolute Exclusion: Known hypersensitivity to human secretin or any constituent of the injection.
- Relative Exclusion: Acute pancreatitis, severe renal impairment (eGFR <30 mL/min), or uncontrolled hypertension.
- Red Flags After Test: Sudden severe abdominal pain, signs of anaphylaxis (urticaria, dyspnoea, hypotension), or hypercalcaemic crisis—go to nearest ER immediately.
- For minor patients, a parent/legal guardian must provide written consent in compliance with Federal Decree‑Law No. 4 of 2016 on Medical Liability.
Patient FAQ & Clinical Guidance
1. Why do I need multiple blood draws for this gastrin test?
The Secretin Stimulation Test requires serial blood samples at baseline and 5, 10, 15, 20, 25, 30 minutes post‑injection to capture the peak gastrin surge that is pathognomonic of a gastrinoma. A single basal gastrin level cannot reliably differentiate true tumour‑driven hypersecretion from common benign causes of hypergastrinemia.
2. How should I prepare for the Gastrin Stimulation test?
You must fast overnight (minimum 8 hours, water allowed) and remain comfortably at rest throughout the entire timed procedure. Our mobile phlebotomist will place a heparin lock for the secretin injection and all subsequent blood draws, ensuring minimal discomfort and strict cold‑chain immediately after collection.
3. What do abnormal results indicate?
A rise in serum gastrin ≥200 pg/mL above fasting baseline within 10 minutes of secretin injection strongly indicates a gastrinoma (Zollinger‑Ellison syndrome) and guides further imaging. A flat or paradoxical response often points to atrophic gastritis, chronic PPI use, or retained antrum syndrome.
