Antigens are specific proteins found on the surface viruses that trigger immunological reactions leading to the production of antibodies in the human body. The recognition of antigens by the immune system and the production of corresponding antibodies forms the basis of rapid antigen tests (RAT). These tests are valuable for rapid screening and detection of disease-causing pathogens making them ideal diagnostic tests for primary screening to aid timely treatment of the patient.
Genes2Me offers numerous CE-IVD marked Antigen-Based Rapid Test Kits based on chromatographic immunoassay in a cassette format, where nitrocellulose membranes are coated with antibodies which interact with specific antigens present in the patient sample. The kits produce results within 15-30 minutes which can be visualised manually or by using an immunofluorescence machine reader.
These tests are ideal point-of-care testing allowing rapid detection of various infectious diseases, particularly viral infections such as influenza, respiratory syncytial virus (RSV), SARS-CoV-2 virus etc.
The compatibility of these kits with various sample types like nasopharyngeal swabs, serum, whole blood, etc. qualify them as reasonably inexpensive and easy testing options.
