The Syphilis/HIV Combo Rapid Test Cassette (Whole Blood/Serum/Plasma) is a qualitative, membrane-based immunoassay for the detection of antibodies to HIV 1.2 and syphilis in whole blood, serum or plasma. The membrane is pre-coated with recombinant HIV antigens in the HIV region and recombinant syphilis antigens in the SYP region. During the test, the whole blood, serum or plasma sample reacts with coated particles and syphilis antigen-coated particles in the test cassette. The mixture then migrates chromatographically on the membrane by capillary action to the HIV antigen line above and reacts with recombinant HIV antigen and syphilis antigen on the membrane in the HIV and SYP line region. If the sample contains antibodies to HIV 1 and/or HIV 2 and/or syphilis, colored lines will appear in the HIV and/or SYP line region, indicating a positive result. If the sample does not contain antibodies to HIV 1 and/or HIV 2 and/or syphilis, colored lines will appear in the HIV and/or SYP line region, indicating a negative result.
HIV and/or syphilis result. As a procedural control, a colored line always appears in the control line region, indicating that the correct sample volume has been added and membrane hydration has occurred
