Frequently Asked Questions
Is fasting required for this test?
Yes, fasting for 8-12 hours is mandatory. Food intake stimulates gastrin release and can falsely elevate results.
What sample is collected?
Venous blood collected in a serum separator tube. Sample should be processed within 2 hours of collection.
What does a high gastrin level indicate?
Markedly elevated fasting gastrin suggests Zollinger-Ellison syndrome (gastrinoma), peptic ulcer disease, or atrophic gastritis. Levels >1000 pg/mL are highly suggestive of a gastrin-secreting tumor.
How long for results?
Reports are available within 24-48 hours via www.drpatholab.in or WhatsApp/Email.
Can medications affect results?
Yes. Proton pump inhibitors (PPIs), H2 blockers, and antacids can significantly raise gastrin levels. Your doctor may advise temporary discontinuation before testing.
Does stress affect gastrin?
Physiological stress, renal failure, and retained acid-inhibiting conditions can elevate gastrin. Clinical correlation and repeat testing may be required.
