Even more noteworthy is during the treatment and detection again, the patients must not received any eradication therapy of Hp. What's more , before the detection, they also has not used antibiotics, bismuth agent and the traditional Chinese medicine with antibacterial effect in 1 monthor and has not used H2RA and PPI in 2 weeks to prevent affecting the accuracy of the results.
