Peratop

The Salmonella typhi test peratop is a CE-marked rapid immunochromatographic assay for qualitative detection of IgG and IgM antibodies to Salmonella enterica serotype Typhi in human serum, plasma, or whole blood, providing results in 15-20 minutes. The test uses recombinant S. typhi antigens immobilized on a membrane to capture specific antibodies, with separate lines for IgG and IgM interpretation. The kit includes individually foil-wrapped test cassettes, sample diluent, disposable pipettes, and package insert. Primary clinical applications include rapid diagnosis of typhoid fever in endemic regions (Indian subcontinent, Southeast Asia, Africa, South America), differentiation of acute (IgM positive) from past infection (IgG only), outbreak investigation and control, screening in febrile patients, travel medicine assessment, antibiotic stewardship, and maternal/child health in endemic areas. Critical safety precautions include proper specimen handling (universal precautions), quality control verification, awareness of window period (repeat testing if early infection suspected), and clinical correlation of results. Essential rapid test for typhoid fever diagnosis in resource-limited and endemic settings.
