General Information

Group A β-hemolytic streptococcus is a bacterium that lives on the surface of the nose, throat and skin of humans. It causes such diseases as tonsillo-pharyngitis, lower respiratory tract infections, whooping cough, impetigo, meningitis, endocarditis, arthritis and others. 20-40% of tonsillo-pharyngitis are of streptococcal origin. Cases of streptococcal tonsillo-pharyngitis are more common in children aged 5 to 15 years. The causative agent is spread both by air-droplet (coughing, sneezing, talking) and by contact (touching infected surfaces, close contact with infected people, using their personal belongings). In untreated cases, complications develop in the form of rheumatic fever, glomerulonephritis, streptococcal abscesses.

When should we take the test?

Streptococcal infection is characterized by such symptoms as:

  • Throat membrane
  • Difficulty swallowing
  • Fever
  • Swelling and pain of the neck and submandibular lymph nodes
  • Rash on the skin
  • Headache and abdominal pain
  • Ingratitude
  • Swelling/hyperemia of tonsils and purulent plaques
  • plastered tongue

The golden standard of diagnostics is the rapid test of group A β-hemolytic streptococcus, which identifies the streptococcal antigen (protein) by immunochromatographic method, which allows to diagnose the disease in 15-30 minutes. Throat smear is the research material for tonsillo-pharyngitis.

A throat swab culture study is also used. A streptococcal culture confirms a streptococcal infection. Research time 24-48 hours.

Possible interpretation of the results

 

    • The test is positive if the control and test lines are colored. A faintly expressed test line also corresponds to a positive response. (Presence of streptococcal antigen was confirmed).

    • The test is negative if only the control line is colored (presence of streptococcal antigen was not confirmed)

  • The test answer is unreliable if:
    Test and control lines are not visible
    The test line is colored, while the control line is not visible

The test is an immunodiagnostic method based on antigen detection, which enables the diagnostics of streptococcal infection in 15-30 minutes. It is easily done. Efficiency 95%.
