A family of rapid, sensitive agglutination tests providing identification of b-hemolytic streptococci belonging to Lancefield groups A, B, C, D, F and G. Identification is based on the type of hemolysis (ß-hemolysis) surrounding colonies grown on blood agar and on the detection of group-specific polyoside antigens in the cell wall. The polyoside antigens are extracted from the cell wall and their presence demonstrated using latex particles coated with homologous antibodies.

Extraction can be performed at two temperatures:
– |
15 minutes at room temperature
|
– |
10 minutes at 37°C |
