title: [The study of the presence of HpSA antigens in the faeces in Helicobacter pylori infection].
abstract: A total of 154 adult patients with dyspeptic symptoms were studied. In case of 115 (74,68%) persons Helicobacter pylori infection was detected, taking into consideration positive results in a rapid urease test and histological examination and presence of antibodies in the serum. In 69,6% predominated high (> 72 IU/ml) level specific anty-H. pylori antibodies. In stool, antigen H. pylori was detected in 100 (64,9%) samples. In 137 cases were obtained results, this same like results of three early tests. Senitivity and specificity of HpSA test were 86,21% and 98,18%, respectively. It was significant (13,91%) percenage of false negative results.
