Streptococcal screen
Definition:
A streptococcal screen is a test to detect streptococcal pharyngitis from a throat swab. Alternative Names:
Rapid strep test Text Continues Below
How the test is performed:
The test requires a throat swab. Antibody-antigen technology is used to identify the presence of group A streptococcus from the swab. The test takes about 7 minutes. A culture for group A streptococcus is often done at the same time, because the rapid test may miss some infections. How to prepare for the test:
There is no special preparation. Inform the health care provider if you are taking, or have recently taken, antibiotics. How the test will feel:
Your throat will be swabbed in the area of the tonsils. This may make you gag. Why the test is performed:
The test is performed when strep throat is suspected or when symptoms of pharyngitis (sore throat) are present.
