DIAGNOSTIC CHARACTERISTICS OF A LATEX ANTIGEN HELICOBACTER TEST-SYSTEM

Abstract

Purpose: The study of operation diagnostic characteristics of a newly constructed helicobacter test-system which is designed to determine the total antibodies in the blood serum in volumetric agglomeration reaction.Materials and methods: Blood sera of 224 gastroenterological patients were studied with the help of diagnostic system constructed. Commercial immune-enzyme blood assay systems were used to be the referent method.Results: Diagnostic operation characteristics of a latex antigen helicobacter test-system were determined with the help of referent serological diagnostic methods. At the cut-off point 1:160 the sensitivity, specificity and diagnostic effectiveness are 94,9%, 79,3% и 88,2%, respectively.Summary: The cut-off point 1:160 is shown to be used as a diagnostic threshold.
