Rapid Group A Strep Test
The Rapid Strep Test allows for a quick diagnosis of Group A Streptococcus directly from throat swabs. The rapid test uses an immunoassay to detect group A streptococcal antigens. The dipstick contains a membrane strip that has been coated with colored anti-Strep A antibodies. If the specimen being tested contains Group A Strep bacteria, the Strep A antigens extracted from the throat swab will react with the antibodies, producing a pink-purple line. Thus, a pink to purple line at the test line region of the dipstick is positive for Group A Strep. (Note: A control line will always appear on the dipstick to demonstrate the test is working properly.)
This Rapid Strep Test is positive for Group A Streptococcus. Note the appearance of both the Control line and the Test line on the dipstick.
