Comparative Study on Cost and Effects of Non Invasive Helicobacter Pylori Diagnostic Tests
Helicobacter pylori is the most common microorganism which colonizes in gastrointestinal system. There are different methods for diagnosis of infection such as rapid stool antigen, urea breath and serology tests. The purpose of this study was comparing the cost and effectiveness of these methods.
94 dyspeptic patients with mean age of 46 ± 14 years, were evaluated. The patients were considered infected when the results of 2 tests (rapid stool antigen test, urea breath test, rapid urease test and histology) was positive.
Accuracy of rapid stool antigen test was 91%, urea breath test was 82% and serology was 52%.
As the cost of stool antigen test was minimum, it is concluded that rapid stool antigen test is more cost-benefit, accurate and reliable test for diagnosis of helicobacter pylori compared with urea breath test and serology.
