Enhancing the value of biposy urease test by two biposy specimen collection in the diagnosis of H. pylori infection on peptic ulcer disease patient

200 patients over 18 years old were diagnosed with peptic ulcer. Two specimens were taken on each patient: from the corpus and 1/3 andral, which were put into each urease test hole. The results were diagnosed with H. pylori infection with urease test by reading biopsyspecimen after 1 hour and 24 hours. With 83.5% patient having used drugs before endoscopy, the percentage of H. pylori (+) from the corpus and the antral specimen is significantly different (65% vs 68.5%) but using specimens from both sites increases significantly the H. pylori positivity from 65% to 78%
