Proper diagnosis and management of these conditions are essential for patient health.
The Gastrin Test is a valuable tool in assessing and treating stomach acid-related disorders.

Gastrin Test Purpose

The purpose of the Gastrin Test is to:

Assess and monitor stomach acid production.

Gastrin Test Preparation

Here is the basic preparation for the Gastrin Test.

Before Test

In most cases, you'll need to fast for a specific period before the test, typically around 12 hours.
Inform your healthcare provider about any medications or supplements you're taking, as some can affect test results.

During Test

The test usually involves a blood draw, where a sample is collected from a vein in your arm.

After Test

You can resume your normal activities and diet after the blood draw.
Your healthcare provider will interpret the results and discuss any necessary follow-up actions or treatment.

Gastrin Test Procedure

Here is the basic Gastrin Test Procedure.

A healthcare provider will clean the area and insert a needle into a vein to draw blood.
The blood sample is then sent to a laboratory for analysis.
In the laboratory, the concentration of gastrin in the blood is measured.
Results are typically available in a few days.
Your healthcare provider will discuss the results with you and may recommend further evaluation or treatment if necessary.

Gastrin Test Result

Gastrin test results are reported as a numerical value, typically in picograms per millilitre (pg/mL).

Normal values can vary depending on the laboratory and the specific test used.
Elevated gastrin levels may suggest conditions like gastrinomas or Zollinger-Ellison syndrome.
Your healthcare provider will interpret the results in the context of your medical history and clinical symptoms.
Further diagnostic tests or treatments may be recommended based on the gastrin test findings.

Gastrin Test Normal Range

Here is the normal range of the Gastrin Test

Age Group	Normal Range (pg/mL)
Adults	0-180
Children	0-125

Gastrin Test Interpretation

Here is the Interpretation of the Gastrin Test.

Gastrin Level	Interpretation
Elevated	May indicate GI disorder.
Normal	Within expected range.
Low	Uncommon; needs review.

Gastrin Test High Levels

Here are potential causes of high gastrin levels.

Potential Cause	Description
Zollinger-Ellison Syndrome	A rare condition causing excessive gastrin production.
Pernicious Anemia	Reduced stomach acid secretion leading to gastrin increase.
Chronic Kidney Disease	Impaired kidney function affecting gastrin clearance.
Chronic Atrophic Gastritis	Inflammation and damage to the stomach lining.
Gastrinoma	Tumor (gastrin-producing) in the pancreas or duodenum.
Chronic Use of Proton Pump Inhibitors	Medications that can stimulate gastrin release.
Stress or Trauma	Temporary elevation due to stress or trauma.

Gastrin Test Low Levels

Here are potential causes of low gastrin levels.

Potential Cause	Description
Achlorhydria	Absent or very low stomach acid production.
Antacid Medications	Use of medications that reduce stomach acid.
Chronic Atrophic Gastritis	Severe damage to the stomach lining.
Hypothyroidism	Reduced thyroid function affecting gastrin.
Helicobacter pylori Eradication	Successful treatment of H. pylori infection.
Chronic Kidney Disease	Impaired kidney function affecting gastrin clearance.
Long-term PPI Use	Extended use of proton pump inhibitors.

Specimen Requirements For Gastrin Test

Here are the specimen requirements for the Gastrin Test.

Specimen	Serum
Volume	1 ml
Container	Red-top tube or gel-barrier tube
Collection	Freeze immediately and maintain frozen until tested. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
Storage	freeze.
Sample Stability	Temperature	Period
	Frozen	14 days
	Freeze/thaw cycles	Stable x3
Causes for Rejection	Gross hemolysis; patient not fasting; specimen not received frozen; gross lipemia; plasma specimen.

Gastrin Test is Safe?

The Gastrin Test is generally safe.

It involves a routine blood draw, which carries minimal risk and is well-tolerated by most individuals.
The procedure is considered safe for assessing stomach acid-related issues.

When Do You Get Gastrin Test Results?

Gastrin test results are generally available in about 1 to 2 days.
Reporting times may vary depending on the specific laboratory.

Gastrin Test Limitation

Here is the basic limitation of the Gastrin Test.

Limited specificity: Elevated gastrin levels can result from various gastrointestinal conditions, not exclusive to gastrinomas.
Interference with medications: Certain drugs can affect gastrin levels, potentially complicating interpretation.
Doesn't diagnose tumors: The test identifies high gastrin levels but doesn't confirm the presence of tumors directly.
False positives: Non-gastrinoma factors can occasionally elevate gastrin levels, leading to false positives.
Not a standalone diagnostic: Additional tests, such as imaging, are often needed to confirm diagnoses.

Gastrin Test Risk Factors

Here are some of the risk factors of the Gastrin Test.

Non-specific for gastrinomas.
Medications can affect gastrin levels.
Doesn't directly confirm tumor presence.
Potential for false positives due to other factors.
Often used in conjunction with imaging for diagnosis.

Doctor Recommendations After Gastrin Test Result

Here are the Doctor's recommendations or consult a specialist after the Gastrin Test.

Gastrin Test	Doctor to Visit	Reason
High Values	Gastroenterologist or Surgeon	Evaluate and manage gastric disorders.
Normal Values	No specific specialist	Based on clinical context and symptoms.
Low Values	No specific specialist	Based on clinical context and symptoms.

Gastrin Test FAQ

What is a Gastrin Test?

A Gastrin Test is a medical diagnostic procedure used to measure the levels of gastrin, a hormone produced by the stomach. Gastrin plays a crucial role in regulating the production of stomach acid. This test is typically ordered to assess gastric function and investigate conditions related to excessive or inadequate stomach acid secretion. It is a valuable tool in diagnosing disorders like Zollinger-Ellison syndrome, peptic ulcers, and gastrinomas.

Why is a Gastrin Test necessary?

Gastrin testing is necessary to evaluate stomach acid production and diagnose related disorders. High gastrin levels may indicate conditions like Zollinger-Ellison syndrome, which leads to excessive acid secretion, while low levels could be a sign of pernicious anemia or atrophic gastritis, causing reduced acid production. Accurate diagnosis helps guide appropriate treatment and management strategies.

How is the Gastrin Test performed?

The Gastrin Test involves drawing a blood sample, usually from a vein in the arm. Fasting for a few hours prior to the test may be required. The collected sample is then sent to a laboratory for analysis. The levels of gastrin are measured, and results are typically available within a few days. In some cases, a stimulated gastrin test, where the patient is given a meal or a hormone to trigger gastrin release, may be performed.

What do abnormal Gastrin Test results mean?

Abnormal results may indicate an underlying medical condition. Elevated gastrin levels could suggest Zollinger-Ellison syndrome, hypercalcemia, or chronic kidney disease. Low levels may indicate pernicious anemia or conditions that reduce acid secretion. Further tests and clinical evaluation are often necessary to confirm a diagnosis and determine the appropriate treatment plan.
