Rapid test with immunological optical technology for the qualitative detection of Group A Streptococcus antigens in pharyngeal tonsillar samples.

The test uses colored particles labeled with antibodies, applied at two distinct points on the device, to produce a red test line in case of a positive result and a blue control line indicating the validity of the test.

Intended use and contexts of application

This in vitro diagnostic (IVD) test is intended for professional use as an aid in the diagnosis of Group A streptococcal pharyngitis. It is indicated for use in pediatric clinics and outpatient facilities, in hospital laboratories, outpatient clinics, emergency departments, and point-of-care settings where qualified personnel perform rapid antigen tests.

Advantages and clinical relevance

The design of the optical double-color immunological test improves visual discrimination between the test and control lines, reducing false negatives while maintaining high specificity. Results are quick and easy to interpret, facilitating timely clinical decisions regarding antibiotic therapy.
