About Group A Streptococcus

Group A Streptococcus is a major cause of upper respiratory infections such as tonsillitis, pharyngitis, and scarlet fever. Early diagnosis and treatment of Group A Streptococcal pharyngitis has been shown to reduce the severity of symptoms and further complications, such as rheumatic fever and glomerulonephritis1.

Conventional methods used for the detection of the disease depend on the isolation and subsequent identification of the organism1,2. These methods often require 24-48 hours to complete. Recent developments of immunologic techniques, which can detect Group A Streptococcal antigen directly from throat swabs, allow physicians to diagnose and administer therapy immediately3,4.

Frequently Asked Questions

If I want to perform bacterial culture in addition to the BinaxNOW® Strep A test do I need to take two swabs from the patient?

Two swabs may be taken but it is possible to use the same throat swab to perform both tests.  Inoculate the blood agar plate first and then perform the BinaxNOW® Strep A test. It is not possible to perform bacterial culture after the BinaxNOW® Strep A test because the organisms will have been killed during the extraction procedure.


A Patient was recently treated with antibiotics but still shows a positive result with BinaxNOW® Strep A.  Bacterial culture was negative.

BinaxNOW® Strep A is an antigen detection test for Streptococcus group A so will detect both viable and non-viable organisms.  The positive result is due to non-viable Streptococcus group A organisms which have not yet cleared from the body. The same is true for any other rapid Strep A test.
