STREPTOP A® is an immunochromatographic test on a membrane, using the sandwich capture method. An anti-streptocoque A antibody is fixed on to the membrane’s test region. A second anti-streptocoque A antibody is conjugated to purplelatex particles and placed just over the membrane’s immersion zone. The presence of a purple line at the test zone level, indicates a positif result, whereas no purple line indicates a negative result. The purple line at the control level, indicates that the test was functional.
INDICATIONS
Only the patients afflicted with an accute angina with group A streptocoques are justifiable for an antibiotic treatment. STREPTOP A® enables to determine with accuracy, the streptococcic origin of an angina.using it systematically, when confronted with any type of angina enables to prescribe the rational amount of antibiotics and contributes to fight efficientlyagainst antibiotic resistance.
The STREPTOP A® test is a qualitative, lateral flow immunoassay for the detection of Strep A antigen in a throat swab. In this test, antibody specific to Strep A antigen is coated on the test line region of the strip. During testing, the extracted throat swab specimen reacts with an antibody to Strep A that is coated onto particles. The mixture migrates up the membrane to react with the antibody to Strep A on the membrane and generate a red line in the test region. The presence of this red line in the test region indicates a positive result, while its absence indicates a negative result. To serve as a procedural control, a red line will always appear in the control region if the test has been performed properly. If a red control line does not appear, the test result is not valid.
Streptococus pyogenes which contains the lance field group A antigen that can cause serious infections such as pharyngitis, respiratory infection, endocarditis, meningitis and arthritis. Rapid diagnosis and early antibiotic therapy of groupe A Straptococcal infection appear to be the best means of preventing medical complications and reducing the spread of the disease.
