Strep A

Introducing the Strep A Rapid Test Cassette

A Rapid Test Cassette is a chromatographic immunoassay for the qualitative detection of Strep A antigens from throat
swab specimens to aid in the diagnosis of Group A Streptococcal infection.

What is the Test?

  • The Strep A Rapid Test Cassette is a rapid test to qualitatively detect the presence of Strep A antigens
    in throat swab specimens, providing results within 5 minutes.
  • The test utilizes antibodies specific for whole cell Lancefield Group A Streptococcus to selectively detect
    Strep A carbohydrate antigens in a throat swab specimen.


*Tests are professional use only under clinical settings.


What is the Disease?

  • Streptococcus pyogenes is an aerobic non-motile gram-positive coccus, which contains the Lancefield group
    A antigens that can cause serious infections such as
    pharyngitis, respiratory infection, impetigo, endocarditis,
    meningitis, puerperal sepsis, and arthritis.
  • The bacterium is transmitted via respiratory droplets, hand contact and nasal discharge – patients suffering from streptococcal pharyngitis are infective during the acute phase of illness (7-10 days) and up to 1 week afterwards.



  • Streptococcus pyogenes causes various infections, with the most common being streptococcal sore throat, marked by fever and swollen tonsils.
  • If left untreated, strep throat can persist for 7-10 days and may lead to serious complications like rheumatic fever and peritonsillar abscess.
  • Less common infections caused by S. pyogenes include septicaemia, otitis media, mastitis, sepsis, cellulitis, erysipelas, myositis, osteomyelitis, septic arthritis, meningitis, endocarditis, pericarditis, and neonatal infections.


Mortality/Morbidity – Clinical Implications

  • S. pyogenes infections vary by location, with streptococcal pharyngitis most common in temperate climates during
    late winter and early spring.
  • Human-to-human transmission, often in crowded settings like schools, leads to over 600 million yearly cases
    of S. pyogenes pharyngitis globally.
  • Severe S. pyogenes infections cause at least 517,000 annual deaths worldwide, with rheumatic fever alone
    accounting for 233,000 of these deaths.

Key Features

  • Rapid detection for the presence of Strep Antigens, providing results from 5 minutes.
  • In-built procedural control.
  • Simple and easy to use test, to be used with throat swab samples.
