Helicobacter pylori Antigen, Stool


Non-invasive testing for H. pylori can be done by Urea Breath Test (UBT), serology, and the detection of H. pylori antigens in body fluids such as saliva, urine and faeces. However, positive results by serology do not necessarily indicate current infection, and UBT is relatively expensive and is not available in most routine laboratories. The presence of H. pylori in faeces is compatible with faecal-oral route of transmission. Thus, the detection of H. pylori antigens in faeces provides economical and diagnostic advantages over other testing methodologies


This test is particularly appropriate for the diagnosis of H. pylori in children or those who prefer providing the sample in the privacy of their homes. However, this test should not be offered to patients on antibiotics, proton pump inhibitors, and bismuth preparations because these substances can inhibit the growth of H. pylori and cause false negative results.
