Methods: 328 patients were measured upper gastrointestinal endoscopic examination which as gold standards and HpSA test in the meantime, comparing accuracy, sensitivity, specificity and other Indicators.
Results: In the diagnosis of Hp infection, HpSA test had no significant difference comparing with gold standards and had a P value of over 0.5. The sensitivity of HpSA test was 94.6%, while the specificity, veracity, expected positive value, and expected negative value were 96.9%, 96.3%, 89.7% and 98.4%, respectively.
