The cost of the HP H. pylori test is more than$100, and what is described is the carbon 13 or carbon 14 breath test. The current recommended test for H. pylori is the carbon 13 or carbon 14 urea breath test, because the sensitivity and specificity is relatively high, and does not require gastroscopy, no pain, so patient compliance is better, but also as the preferred method of review after eradication of H. pylori treatment. The test requires taking one capsule containing carbon 13 or carbon 14 urea orally after two hours on an empty stomach and after a meal, and waiting for about 20 minutes for the test to be performed, and a report will be issued soon to clarify whether H. pylori infection is present.
