Abstract
The aim of this study was to evaluate the diagnostic value of the new motility indole urease (MIU) test and Campylobacter Like Organism (CLO) test with culture as the gold standard. This study were done on 225 biopsy samples from gastric antra taken from chronic dyspeptic patients from several hospitals in Jakarta. On the MIU test, the biopsy tissue sample was submerged in the MIU tube agar to a depth of about 2/3 from the surface, and incubated at room temperature. Another piece of biopsy tissue was used for CLO and cultured. The CLO and MIU tests were considered positive if the color changed from yellow to red, and were considered negative if there was no color change within 24 hours. The CLO test compared with culture had 75.9% sensitivity, 78.6% specificity, 76.6% positive predictive value and 78% negative predictive value, whereas the result of the MIU test compared with the culture method showed 96.3% sensitivity, 82.1% specificity, 83.2% positive predictive value, and 96% negative predictive value. The MIU test with its higher sensitivity and specificity may be used as an alternative diagnostic method for H. pylori infection.
