Principle of the test

The streptococcal grouping method involves chemical extraction of group specific carbohydrate antigens using specially developed nitrous acid extraction reagents. The Extraction Reagents 1 and 2 provided in the kit contain a chemical substance able to extract the Streptococcal group specific antigens at room temperature. Extraction Reagent 3 contains a neutralizing solution. The neutralized extracts can be easily identified using blue latex particles sensitized with purified group specific rabbit immunoglobulins. These blue latex particles agglutinate strongly in the presence of homologous antigen and will not agglutinate when homologous antigen is absent.
