The cost of the C13 breath test is around 100 to 200 dollars, and each hospital charges differently, depending on the local hospital. The C13 breath test is one of the most common methods of H. pylori testing and is internationally recognized as the “gold standard” for H. pylori testing. It is best to fast or abstain from food for 3 hours or more before the test. Antibiotics are prohibited for one month before the test to avoid affecting the test results. If the test value is more than 4dpm/mmol, it suggests that the patient is infected with Helicobacter pylori, and it is recommended that the patient be treated with “quadruple therapy” under the guidance of a doctor, such as Metronidazole, Clarithromycin, Pantoprazole, and Bismuth Potassium Citrate. If the test result is 0-3.9dpm/mmol, it means no infection. Finally, we remind you that it is best to perform regular C13 breath test tests every year. If there is any abnormality, treat and control it in time so as not to delay the condition.
