- gastric acid secretion test
The stomach acid stimulation test is used to evaluate the ability of the stomach to secrete acid.
Who is a candidate for the test?
This test is mainly used to evaluate:
- the cause of ulcers, such as peptic ulcers
- the response of ulcers to treatment
- the cause of a high level of gastrin, an enzyme in the blood
How is the test performed?
A small tube is inserted through the nose and into the stomach. A special medication is then given by injection. This medication normally causes the stomach to make acid.
After the medication has taken effect, a small sample of stomach fluid is removed. This fluid is sent to the lab for analysis. The amount of acid made by the stomach in response to the medication can be measured.
What is involved in preparation for the test?
A person is instructed not to eat or drink for 4 to 6 hours before the test.
What do the test results mean?
The test results show how much acid is made by the stomach in response to the medication. There is a range of acid levels that is considered normal. Some people fall outside of this range for no special reason.
However, if the stomach makes less acid than normal, it may be due to:
If the stomach makes more acid than normal, it may be due to:
