What is serum gastrin levels?

The average normal level of fasting serum gastrin is about 50 pg per ml, and ranges from 20 to 100 pg. The upper limit of normal is 200 pg, and in the presence of gastrinoma (Zollinger-Ellison syndrome), fasting levels may rise to over 7,000 pg (70–80 percent, G 34).

What is high gastrin levels?

Abnormal gastrin production occurs in some clinical and diseased states, a condition known as hypergastrinemia and defined by a Gastrin level greater than 100–150 pg/ml [2].

What is a gastrin blood test used for?

The gastrin test is primarily used to help detect excess production of gastrin and gastric acid. It is used to help diagnose gastrin-producing tumors called gastrinomas, Zollinger-Ellison (ZE) syndrome, and hyperplasia of G-cells.

What causes high serum gastrin?

By far, the two most common causes of high gastrin levels are anti-acid medications you take for reflux or heartburn and a condition called chronic atrophic gastritis. These both can do damage to your stomach lining. They also cause your stomach to make less acid.

What is the definition of gastrin?

Listen to pronunciation. (GAS-trin) A hormone released from special cells in the lining of the stomach after eating. Gastrin causes the stomach to release an acid that helps digest food.

What causes gastrin?

Gastrin is a hormone that is produced by ‘G’ cells in the lining of the stomach and upper small intestine, and released into the blood circulation. During a meal, gastrin stimulates the stomach to release gastric acid (hydrochloric acid).

What is a gastrin blood test called?

Test Code: 004390. Also Known As: gastrin hormone blood levels. Methodology: Immunochemiluminometric assay (ICMA) Preparation: Fasting for 12-14 hours required.

What causes excessive gastric acid?

Eating a heavy meal and lying on your back or bending over at the waist. Snacking close to bedtime. Eating certain foods, such as citrus, tomato, chocolate, mint, garlic, onions, or spicy or fatty foods. Drinking certain beverages, such as alcohol, carbonated drinks, coffee, or tea.

Zollinger-Ellison syndrome is a rare digestive disorder that results in too much gastric acid. This extra gastric acid can cause peptic ulcers in your stomach and intestine. Symptoms include abdominal pain, nausea, vomiting, weight loss, and diarrhea.

What abnormalities might lead to elevated serum gastrin levels?

What increases gastrin?

Gastrin release is also stimulated by the stretching of the stomach walls during a meal, the presence of certain foods (particularly proteins) within the stomach cavity and an increase in the pH levels of the stomach (i.e. the stomach becoming less acidic).
