In vitro diagnostic reagent to aid in the diagnosis of Salmonellosis may exhibit decreased or no reactivity. If proper controls are run with the lot in question, it would become apparent that the antigen is non reactive and patient specimen results should not be reported. If control testing is not performed a salmonella-infected patient could go undiagnosed, with possible adverse effects.
