Abstract
and HM-CAP, but the FLEX PACK assay failed to detect two (33%). Conclusions: (1) The Chiron lysate and HM-CAP are equally sensitive in detecting HP antibody but the lysate assay is twice as specific; (2) the FLEX PACK assay is significantly less sensitive than the other two assays; (3) 29% of pediatric patients with abdominal pain have antibodies to CagA or VacA. These patients are accurately detected by Chiron lysate or HM-CAP assays, but not by FLEX PACK. This study was funded in part by a grant from EPI.
