Clinical value of Helicobacter pylori stool antigen test,ImmunoCard STAT HpSA，for detecting Hpylori infection
摘要
AIM:To evaluate the reliability of the Helicobacter pylori stool antigen test, ImmunoCard STAT HpSA, for detecting Hpylori infection.METHODS:Stool specimens were collected from 53 patients who received upper endoscopy examination due to gastrointestinal symptoms.ImmunoCard STAT HpSA was used to detect Hpylori stool antigens. Hpylori infection was detected based on three different tests:the urease test,Warthin-Starry staining and culture. Hpylori status was defined as positive when both the urease test and histology or culture alone was positive.RESULTS:Sensitivity,specificity,positive predictive and negative predictive values and the total accuracy of ImmunoCard STAT HpSA for the diagnosis of Hpyloriinfection were 92.6% (25/27), 88.5% (23126), 89.3% (25/28), 92%(23/25) and 90.6% (48/53), respectively.CONCLUSION:The stool antigen test, ImmunoCard STAT HpSA,is a simple noninvasive and accurate test for the diagnosis of Hpylori infection.
