Home > Health Library > Rapid Strep Test for Strep Throat
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 in 10 to 15 minutes.
It may be done so your doctor can find out right away whether you have strep throat. There is another test for strep, called a throat culture, but that test takes a few days to get the results.
You don't need to do anything before you have this test.
A normal or negative test means that strep bacteria may not be present.
An abnormal or positive strep test means that strep bacteria are present.
