چکیده
Dear Editor, We read with interest the Iranikhah et al’s article entitled “Stool Antigen Tests for the Detection of Helicobacter Pylori in Children” in the second issue of 2013 of Iran J Pediatr[1] . They have well reported an interesting investigation about the detection of bacterial antigens in stool for diagnosis of helicobacter pylori in children. Also they appropriately used endoscopy and biopsy as a gold standard test for validation of the H. pylori infection and accordingly Statistical indices are calculated. In this study, the sensitivity ,specificity, positive and negative likelihood ratios for H. pylori stool antigen was reported 85%, 93%, 89.7%, and 90% respectively ,while 89.7%, and 90% are not likelihood ratio ,they are positive and negative predictive values.
