One-step immunochromatographic test for the qualitative detection of Streptococcus pyogenes (Group A Streptococcus) from respiratory samples.
Group A Streptococcus (S. pyogenes) is one of the major causes of respiratory infections in the human upper respiratory tract, being the most significant pathogen causing pharyngitis. In the paediatric population, in fact, it is estimated to be responsible for 30% of pharyngitis. Symptoms can become severe if the patient does not receive treatment, so early identification of this pathogen allowing early initiation of antibiotic treatment is of vital importance to prevent the development of these complications.
Conventional methods for Group A Streptococcus testing and identification require 24-28 hours of incubation of cultures from throat swabs and subsequent confirmation of beta-haemolytic colonies as Group A Streptococcus. The Simple/Stick Strep A test is a method using specific antibodies against a specific Group A Streptococcus antigen.
The test detects both viable and non-viable micro-organisms directly from throat swabs or culture colonies within 10 minutes (or less in the case of highly positive samples).
Ready to use
Simple and safe
Swab samples can be transported in a compatible transport medium (Stuart /Amies), as indicated in the product instructions for use.
If it is desired to culture the sample on a blood agar plate, this should be done before running the rapid test, as the dilution buffers would destroy the bacteria and they would not be able to grow on the plate.
It is recommended to use the swabs supplied in the kit or Floqswabs (Copan) with plastic handles. Do not use calcium alginate swabs or swabs with wooden handles.
The Strep A test is designed to test human respiratory specimens of the oropharyngeal swab type immediately after collection. The test can also be used to test otic swabs, endocervical swabs, ulcers and wounds where Group A Strep is suspected, as well as for the confirmation of colonies grown on a culture plate.
