Diseases reference index «Streptococcal screen»

A streptococcal screen is a test to detect group A streptococcus, the most common cause of strep throat.

The test requires a throat swab. It takes about 7 minutes. The swab is tested to identify group A streptococcus.

There is no special preparation. Inform the health care provider if you are taking, or have recently taken, antibiotics.

Your throat will be swabbed in the area of the tonsils. This may make you gag.

Your health care provider may order this test if you have signs of strep throat or if you have symptoms of pharyngitis (sore throat).

The test is considered normal if Group A streptococcus is not present.

An abnormal result means Group A streptococcus is present, and confirms strep throat.

There are no risks.

This test screens for the group A streptococcus organism only and will not detect other causes of sore throat.
