The Sarpra and World Health Organisation approved COVID-19 Antigen Rapid Test is a rapid assay for the qualitative detection of SARS-CoV-2 antigens in nasopharynx specimens
Principle of the Test
COVID-19 Antigen Rapid Test is a rapid membrane-based lateral flow immunoassay for the qualitative detection of SARS-CoV-2 antigens in human nasopharyngeal swab specimens. During testing SARS-CoV-2 antigens possibly present in the specimen react with the antibody-coated nanoparticles present in the test. The resulting complex chromatographically migrates upward in the strip membrane by capillary action.
If the specimen contains SARS-CoV-2 antigens, they will bind to the SARS-CoV-2 antibodies coated on the (T) Test line region and generate a colored line on the test strip, indicating a positive result. If the antigens are not present in the specimen, no colored line will appear in the (T) Test line region, indicating a negative result. As a procedural control, a colored line will always appear in the (C) Control line region, indicating that the test procedure has been performed properly and that test components have operated as intended.
COVID-19 Antigen Rapid Test
– high Sensitivity and Specificity standards, when compared to a PCR Methodology;
– safe and accurate results in just 15 minutes;
Why using a COVID-19 antigen test?
The use of a COVID-19 Antigen Rapid Test allows to detect the presence of SARS-CoV-2 virus antigens in our body and to take initial precautionary isolation measures in order to reduce further spread of the virus.
