Strep-A (Streptococcal) Tests
For a rapid strep test, the throat and tonsils are swabbed to collect bacteria from the infected area for testing. The bacteria are analyzed to see whether Group A strep (streptococcal) bacteria are causing the sore throat.
A good sample of throat secretions is needed to make sure the test is accurate. A person must remain very still during the procedure so that the doctor is able to collect enough secretions for an accurate test. Results of a rapid strep test are available normally in 10 to 15 minutes.
