BioSign® Strep A

BioSign® Strep A is a rapid immunochromatographic assay for the detection of group A streptococcal antigen directly from throat swab specimens. The test is intended for use as an aid in the early diagnosis of group A streptococcal infection.

Group A streptococcus is one of the most significant human pathogens causing acute pharyngitis, tonsillitis, impetigo, and scarlet fever. It is very important to differentiate streptococcal infection from other etiologic agents (e.g., viral, mycoplasmal, or chlamydial) so that appropriate therapy may be initiated. Early diagnosis and treatment of group A streptococcal pharyngitis infections will reduce the severity of symptoms and further complications such as rheumatic fever and glomerulonephritis. Unlike classical methods for identification, which require 18–48 hours of culture time for throat swab specimens or other exudates to produce results showing bacitracin susceptible beta-hemolytic streptococci, the BioSign® Strep A test requires only 5~10 minutes after collection of the specimen.
