Answer

This novel rapid test is based on monoclonal antibody immunochromatography of stool samples. The test has been reported to be very specific (98%) and sensitive (94%).The results are positive in the initial stages of infection and can be used to detect eradication after treatment.

Although the H pylori fecal antigen test is an interesting tool, information about the cost of the test is pending.
