The ASO latex test kit serology kit is intended for the qualitative and semi-quantitative measurement of antibodies to streptococcal exoenzymes in human serum.
INTRODUCTION
The group A -hemolytic streptococci produces various toxins that can act as antigens. One of these exotoxins Streptolysin O was discovered by Todd in 1932. 1
A person infected with group A -hemolytic streptococci produces specific antibodies against these exotoxins, one of which is antistreptolysin O (ASO). The quantity of this antibody in a patient’s serum will establish the degree of infection due to the -hemolytic streptococcal. 2
The usual procedure for the determination of the antistreptolysin titer is based on the inhibitory effect that the patient’s serum produces on the hemolytic power of a pretitrated and reduced Streptolysin O. 2-6 However, the antigen-antibody reaction occurs independently of the hemolytic activity of Streptolysin O. 7 this property enables the establishment of a qualitative and quantitative test for the determination of the ASO by agglutination of latex particles on slide. 2.
