the result is negative. It indicates that the concentration of the group A streptococcal antigen is zero
or below the detection limit of the test.
Positive Test Result
If two color bands are visible both in the test (T) band and the control (C) band, the result is positive.
It indicates that you may be in a stage of Strep A infection and should consult with your doctor.
Invalid Test Result
No visible band at all, or there is a visible band only in the test region but not in the control region.

Group A Streptococcus is one of the most significant human pathogens causing acute:

Why should I test for Strep A?
It is very important to differentiate streptococcal infection from other etiologic agents (e.g., viral, mycoplasmal,
or chlamydial) so that appropriate treatment can be sought.
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. So it is useful having a home test within reach to be able to make a diagnosis at the first sign of symptoms.
