TEST PRINCIPLE : The OnSite Dengue Ag Rapid Test4.0 is a lateral flow chromatographic immunoassay. The test strip in cassette device consists of: 1) a burgundy colored conjugate pad containing antibodies to dengue NS1 antigen conjugated with colloidal gold (dengue Ab conjugates) and a control antibody conjugated with colloidal gold, 2) a nitrocellulose membrane strip containing a test line (T line) and a control line (C line). The T line is pre-coated with antibodies to dengue NS1 antigen, and the C line is pre-coated with a control line antibody. The antibodies to dengue NS1 recognize the antigens from all four dengue virus serotypes. When an adequate volume of specimen is dispensed into the sample well of the test cassette, the specimen migrates by capillary action across the cassette. Dengue NS1 antigens, if present in the specimen, will bind to the Dengue Ab conjugates. The immunocomplex is then captured on the membrane by the pre-coated antibodies to dengue NS1 antigens forming a burgundy colored T line, indicating a dengue Ag positive test result and suggesting an early acute primary or secondary infection. Absence of the T line suggests a negative result. The test contains an internal control (C line) which should exhibit a burgundy colored line of the immunocomplex of the control antibodies, regardless of color development on the test line (T line). If the C line does not develop, the test result is invalid, and the specimen must be retested with another device. dengue,Dengu,dengue,Dengue card,Dengue cards,Dengue for elisa,Rapid dengue,Dengu miller,Dengue kit,Dengue rapid kit
