The Thermo Scientific™ Streptex™ Rapid Latex Agglutination Test provides a fast, qualitative method for identifying Streptococcus Lancefield Groups A, B, C, F, and G. This test incorporates an acid extraction method to quickly extract group-specific antigens from cultured streptococci without the need for incubation. When mixed with latex particles coated with group-specific antibodies, strong agglutination occurs in the presence of homologous antigens.
Ideal for diagnostic laboratories requiring high sensitivity, rapid processing, and clear visual results, the Streptex Rapid test is validated with >99% sensitivity and supported by over 50 years of proven clinical use. It eliminates the need for control latex and supports flexible sample handling from selective and non-selective media.

Intended Use
The Streptex™ Rapid Latex Agglutination Test is intended for the qualitative identification of Streptococcus species belonging to Lancefield Groups A, B, C, F, and G from isolates grown on culture media. The test is used as part of a diagnostic workflow to support treatment decisions for bacterial infections. It is not a companion diagnostic and is not intended for home or point-of-care use.
Applications
-
Clinical Diagnostics
- Identify Group A strep (e.g., S. pyogenes) in pharyngitis or skin infections
- Detect Group B strep (e.g., S. agalactiae) in prenatal screening
-
Microbiology Laboratories
- Differentiate beta-hemolytic streptococci using a simple, rapid format
- Screen isolates from selective or non-selective agar
-
Public Health & Hospital Labs
- Surveillance and identification of streptococcal pathogens in outbreak scenarios
The Thermo Scientific™ Streptex™ Rapid Latex Agglutination Test provides an efficient and cost-effective solution for the quick identification of clinically significant streptococcal groups. By eliminating incubation time and control latex, and ensuring high sensitivity and specificity, this kit enhances the workflow in clinical and diagnostic laboratories handling streptococcal infections.
