Drinking a small amount of water before the c13 breath test usually has little effect.
The c13 breath test is a simple and effective method of detecting H. pylori bacteria. When doing the test, you need to fast or abstain from food for 8 hours, and drinking a small amount of water will not affect the test.
Before the test, a capsule is taken with a small amount of water. The capsule contains urea, which contains C13, and since H. pylori can break down urea into carbon dioxide, the carbon dioxide produced by the body’s metabolism contains carbon dioxide labeled with C13 as the basic element, and the increase in the amount of carbon dioxide containing C13 is measured by a comparison of the composition of the gas in the second breath with the first breath to determine whether H. pylori is infected. Helicobacter pylori infection.
If you feel dry mouth or thirsty before the test, you can use a cotton swab moistened with water and apply it to the mouth and lips to relieve the symptoms or drink a small amount of water, which generally will not affect the results.
