Rapid test for the detection of group A ß-hemolytic Streptococcus in throat swab. For professional in-vitro diagnostic use only
Group A ß-haemolytic streptococcal infection in the throat (also known as Streptococcus pyogenes) is the most common bacterial cause of acute pharyngitis and is also responsible for some skin infections such as impetigo and erysipelas.
read moreMost types of sore throat are instead caused by viral infections, which heal without the need for antibiotic treatments, which would therefore be useless. Strep A infections can subside within days without treatment, although doctors typically prefer to prescribe antibiotics to prevent infection-related complications that can be serious, such as rheumatic fever or acute glomerulonephritis.

STREP A RAPID TEST is an immunochromatographic test aimed at monitoring the possible bacterial origin of a pharyngitis.
read moreUnderstanding whether a sore throat is caused by the Strep A bacterium or other germs allows you to identify, or rule out, a possible antibiotic treatment.
STREP A RAPID TEST is a rapid immunochromatographic test for the qualitative lateral flow determination of Strep A antigen in a throat swab. In this test, the specific anti-Strep A antigen antibody is adhered to the test area. During testing, the throat swab specimen reacts with anti-Strep A antibody attached to colloidal gold particles.

The test has been carried out correctly when the instructions for use are followed. It includes the reading time and the interpretation of the results shown at the "RESULTS INTERPRETATION" section of the instructions for use.
A colored line will appear at the control region (C) on the test device, showing that the test performed correctly. The absence of the colored line suggests to repeat the test with a new device and a new sample.
The color and intensity of the lines do not affect the interpretation of the result. The test has to be considered positive regardless of the color intensity of the test line (T).
