Why is identification of streptococcal infection important? Patients benefit both immediately and potentially in the long-term by rapid confirmation of streptococcal cause of their sore throat.
What does the rapid strep test detect?
Strep tests are used to determine whether your sore throat is strep throat, an infection of the throat and tonsils caused by group A strep (GAS). Rapid strep tests—a rapid antigen detection test (RADT) can be used to detect group A strep proteins (antigens). Results are typically available in 10-20 minutes.

However, the sensitivity of most current rapid strep tests ranges from 90 percent to 95 percent, so there is a greater chance of false negatives.
