Description
Gastrin
Sample Type:Serum
Tests Included:
Measurement of gastrin levels in the blood.
Sample R
equired:
Blood sample
Test Time:
Results are typically available within a few days.
Test Range Values:
Normal fasting gastrin levels are usually less than 100 pg/mL. There may be a small variance in the reference range between laboratories.
What is the test?
The hormone called gastrin controls the amount of acid produced in the stomach. This test measures the levels of gastrin in the blood, aiding in the diagnosis of conditions related to the stomach and intestines, such as gastrinomas (tumors that produce gastrin) or other disorders affecting stomach acid production.
Test Procedure:
A blood sample is drawn from a vein, and the concentration of gastrin is measured in the laboratory.
When to take the test:
This test is often performed when investigating symptoms related to excessive stomach acid, ulcers, or when a healthcare provider suspects gastrinoma.
Who should take the test:
Individuals showing symptoms like persistent abdominal pain, ulcers not responding to treatment, or those suspected of having gastrinomas might be recommended to take this test.
Precautions for exceptional cases (pregnancy, etc.):
Gastrin testing is generally unrelated to pregnancy. Pregnant individuals should inform their healthcare provider about their pregnancy status.
Frequently Asked Questions (FAQs) for Gastrin Test:
Q1: How does high gastrin levels affect the body?
A: Elevated gastrin levels can lead to increased stomach acid production, potentially causing ulcers, acid reflux, or gastritis.
Q2: Can certain medications affect gastrin levels?
A: Yes, medications like proton pump inhibitors (PPIs) used to reduce stomach acid can sometimes elevate gastrin levels.
Q3: Can dietary habits impact gastrin levels?
A: Dietary factors might stimulate gastrin release, but their direct impact on gastrin levels might be limited. Spicy foods or high-protein meals can transiently increase gastrin secretion.
Q4: What do low gastrin levels indicate?
A: Low gastrin levels might suggest certain conditions affecting gastrin production, such as chronic atrophic gastritis or conditions affecting the cells that produce gastrin.
Q5: Is gastrin testing commonly used in routine check-ups?
A: Gastrin testing is not typically part of routine check-ups. It’s ordered when specific stomach-related symptoms or conditions are suspected
