For nucleic acid tests, two different binding principles are available: nucleic acid lateral flow (NALF) tests and nucleic acid lateral flow immunoassay (NALFIA). NALFIA is a test that combines lateral flow technology and the immunoassay principle to detect nucleic acid-related products like PCR products and genetic amplicons. https://www.cd-diatest.com/services/custom-lateral-flow-nucleic-acid-assay-service.html
