Description
A Helicobacter pylori test detects this common stomach bacteria to diagnose ulcers or gastritis—patients in China needing diagnosis or treatment follow-up can arrange hospital testing with ChinaMedicalHub support for costs typically ranging from ¥200 to ¥500.
Main Uses
Helicobacter pylori testing is primarily used for diagnosing H. pylori infections, which are associated with peptic ulcers, chronic gastritis, and an increased risk of gastric cancer. It is also used to monitor the effectiveness of eradication therapy and to screen individuals at higher risk for these conditions, such as those with a family history of gastric cancer or unexplained gastrointestinal symptoms.
Normal Range
The normal range for Helicobacter pylori (H. pylori) testing is negative, indicating no presence of the bacteria. For specific tests like the urea breath test, a result below 4 or 5 delta over baseline (DOB) is typically considered negative.
Low Values - Possible Causes
A low value, which indicates a negative result, can be due to: absence of H. pylori infection, successful eradication following treatment, natural clearance of the bacteria by the immune system, recent use of antibiotics or proton pump inhibitors that may suppress bacterial activity, or incorrect sample collection or handling.
High Values - Possible Causes
A high value, indicating a positive result, can be caused by: active H. pylori infection, reinfection after previous treatment, resistance to antibiotics used in prior treatments, incomplete eradication therapy, or contamination during the testing process.
