Helicobacter Pylori 23S rRNA/gyrA Gene Mutation Detection Kit (Fluorescence PCR Fusion Curve Method)

A Multicenter Clinical Study of Helicobacter Pylori 23S rRNA/gyrA Gene Mutation Detection Kit (Fluorescence PCR Fusion Curve Method)

The purpose of this study was to evaluate the detection ability of Helicobacter pylori 23S rRNA/gyrA gene mutation detection kit (fluorescent PCR fusion curve method) for Helicobacter pylori gene mutation.

After being informed about the study and potential risks, all patients giving written informed consent will undergo a 1-week screening period to determine eligibility for study entry. At week 0, patients who meet the eligibility requriment will be included in this simultaneous blind test.

Inclusion Criteria:

• 1. patients with Helicobacter pylori infection who need gastroscopy; 2. patients with positive Helicobacter pylori culture in gastric mucosa 3. Helicobacter pylori negative patients

Exclusion Criteria:

• 1.Patients with insufficient fecal samples collected 2.Patients with contraindication of gastroscopic biopsy
