Rapid Latex Agglutination Test for Identification of Streptococcal Groups A, B, C, D, F, and G
The Thermo Scientific™ Oxoid™ Streptococcal Grouping Kit provides a rapid, sensitive, and easy-to-use latex agglutination method for the identification of streptococcal Lancefield groups A, B, C, D, F, and G. The test uses latex particles coated with group-specific antibodies, which agglutinate visibly in the presence of homologous streptococcal antigens.
Designed to enhance diagnostic workflows in microbiology labs, this kit delivers clear results in just two minutes, allowing for rapid classification of streptococci from cultured isolates. An enzymatic extraction procedure is included to improve antigen release, especially for group D streptococci, improving yield and shortening turnaround time.
Key Features & Benefits

Intended Use
A qualitative latex agglutination test designed for the identification of Lancefield streptococcal groups A, B, C, D, F, and G from bacterial colonies cultured on agar. This kit is used as part of a diagnostic workflow to aid clinicians in the diagnosis and treatment of streptococcal infections, such as:
- Pharyngitis
- Scarlet fever
- Otitis media
- Meningitis
- Pneumonia
- Neonatal sepsis
- Endocarditis
- Skin and soft tissue infections (e.g., impetigo, cellulitis, necrotizing fasciitis)
For professional use only. Not intended for automated systems or direct-from-specimen testing.

Test Principle
The test uses latex particles coated with specific antibodies against streptococcal group antigens. When mixed with a suspension prepared from streptococcal colonies, the presence of the corresponding group antigen causes visible agglutination. In the absence of matching antigen, the suspension remains smooth.
- Latex-coated antibodies: Specific for group A, B, C, D, F, and G antigens
- Enzymatic extraction: Ensures optimal antigen yield for reliable results
Required Materials (Not Included)
- Microbiology workstation
- Pipettes or disposable droppers
- Slides or disposable reaction cards
- Incubator and standard agar media (for initial culture)
Warnings and Precautions
- For in vitro diagnostic use (IVD)
- For trained laboratory professionals only
- Results should be interpreted in conjunction with culture morphology, Gram stain, and biochemical tests
- Do not use if the reagents or packaging appear compromised
- Follow standard biosafety and disposal protocols
The Oxoid™ Streptococcal Grouping Kit is a reliable, rapid, and sensitive diagnostic tool for identifying streptococcal Lancefield groups A, B, C, D, F, and G. With its latex-based agglutination format, ease of use, and strong performance, it is an ideal solution for clinical microbiology labs requiring fast turnaround and high specificity in the identification of beta-hemolytic streptococci.
