Stool antigen detection versus C-urea breath test for non-invasive diagnosis of pediatric infection in a limited resource setting.

Introduction: The prevalence of childhood infection with is high, especially in developing countries. Non-invasive methods for detection of infection in children should be inexpensive, easy to perform, well tolerated and have a high diagnostic accuracy. We aimed to compare the reliability, specificity and sensitivity of the stool antigen (HpSA) test with the C-urea breath test (C-UBT) for the diagnosis of infection in a limited resource setting.
