Ultrasound enhancement of Neisseria meningitidis serogroup detection using the Pastorex reagent and serogroup Y and W135 specific latex particles coated in house

Latex reagentLATUSELATUltrasonic improvement
Detection limits are the highest dilution (lowest concentration) of positive antigen control (Pastorex kit) at which agglutination could be detected on a test card compared with phosphate buffer.
LAT, latex agglutination test; USELAT, ultrasonic standing wave enhanced latex agglutination test.
