Gastrin is a hormone that your stomach makes to stimulate the release of gastric acid. This acid helps your body break down and digest food. The gastrin test measures the level of gastrin in your blood to help diagnose certain digestive disorders.
Too much gastrin can cause Zollinger-Ellison syndrome, a rare disease that often leads to ulcers in the stomach and small intestine. It also increases the risk of tumors in the pancreas and duodenum. Too little gastrin can cause problems such as atrophic gastritis, a condition where the stomach lining is thin and weak.
The Gastrin test is a blood test that measures the level of gastrin in your blood. Gastrin is a hormone that stimulates the stomach to produce gastric acid.
This test is usually ordered if a patient has recurrent peptic ulcers or an unusually high amount of gastric acid. It can help diagnose conditions like Zollinger-Ellison syndrome.
A healthcare professional will draw a blood sample from a vein in your arm using a needle. The procedure takes only a few minutes and causes minimal discomfort.
High gastrin levels may indicate conditions like gastrinomas, Zollinger-Ellison syndrome, or atrophic gastritis. Low levels may be due to conditions like pernicious anemia or an underactive parathyroid gland.
Your doctor will discuss the test results with you. If the results are abnormal, you may need further tests to determine the cause and appropriate treatment.
The risks associated with a blood draw are minimal. They include slight pain or bruising at the needle site and, in rare cases, infection.
A normal result indicates that your gastrin levels are within the normal range. However, if you continue to experience symptoms, your doctor may order additional tests.
Yes, certain medications can affect the results of a gastrin test. It's important to inform your doctor about all the medications you are taking.
If your test results are abnormal, you should consult a gastroenterologist. They specialize in digestive system disorders.
The frequency of the gastrin test depends on your symptoms and the doctor's discretion.
Symptoms like recurrent stomach ulcers, diarrhea, heartburn, or abdominal pain might warrant a gastrin test.
Your doctor may order additional tests such as a stomach acid test, CT scan, or MRI to evaluate your digestive system further.
Treatment depends on the underlying cause. It may involve medication, dietary changes, or in some cases, surgery.
You may be asked to fast (not eat or drink) for a period of time before the test. Be sure to follow all instructions from your healthcare provider.
Factors that can affect the results include the use of certain medications and the consumption of food or drink before the test.
Understanding your gastrin levels can be a crucial step in identifying potential digestive disorders. While elevated or low levels of gastrin might be concerning, remember that this test is just one aspect of a comprehensive diagnostic process. Work with your doctor to understand what these results mean in the context of your symptoms and overall health.
