| About HpSA ® |
|
HpSA® (H. pylori Stool Antigen) is a non-invasive, patient-friendly test that detects an active H. pylori infection. It is as simple as serology, can be used regardless of prior testing or treatment and detects active infection as effectively as UBT with less potential for false-negative results while taking acid supression or bismuth medications. The sensitivity and specificity exceed 90%. HpSA® detects H. pylori antigen directly from a fresh or frozen stool specimen, and the patient can collect the sample in the privacy of their home.
