Diagnostic accuracy of a new non-invasive enzyme immunoassay for detecting Helicobacter pylori in stools after eradication therapy

Evaluation of Helicobacter pylori stool antigen test before and after eradication therapy

“…Ishihara et al . have also reported that the sensitivity and specificity of the HpSA test was 90% and 98%, respectively 24 . The results of this study support these findings.…”

Does N‐acetyl Cystein Affect the Sensitivity and Specificity of Helicobacter pylori Stool Antigen Test?

“…Ishihara et al. reported in their studies with 112 cases that diagnostic sensitivity and specificity after eradication therapy was 90% and 98%, respectively [20]. On the other hand some clinical studies showed lower performance in terms of sensitivity and/or specificity, highlighting the need for further studies for methods to increase the accuracy of this noninvasive test [18,21–26].…”

Efficacy of Helicobacter pylori eradication on platelet recovery in children with chronic idiopathic thrombocytopenic purpura

“…The diagnostic accuracy of HpSA is also comparable (sensitivity 92.6%, specificity 100%) with that of other diagnostic tests (14,19,20). The HpSA test has already been used in a few studies to monitor the efficacy of eradication therapy (21)(22)(23). In recent reports it has been suggested that there is an association between H. pylori infection and ITP (24)(25)(26) whereas other reports show no evidence of any such association (27,28).…”
