The HIVSav 1/2/0 Rapid Test is a rapid chromatographic immunoassay for the qualitative detection of antibodies to HIV-1, HIV-2, and Subtype O in whole blood, serum or plasma to aid in the diagnosis of HIV infection.
The detection limit of COMBI Hb-TRANSFERRIN FECAL is 5.1ug/g faeces for human haemoglobin and 0.4ug/g faeces for human transferrin.
Principle Of The Test
The HIVSav 1/2/0 Rapid Test is a qualitative, membrane based immunoassay for the detection of antibodies to HIV-1, HIV-2, and Subtype O in whole blood, serum or plasma. The membrane is pre-coated with recombinant HIV antigens in the test line regions, T1 and T2. The T1 test line is pre-coated with HIV-1 and Subtype O antigen and the T2 test line is pre-coated with HIV-2 antigen. During testing, the whole blood, serum or plasma specimen reacts with the mixture of HIV-1 envelope and core antigens and HIV-2 envelope antigen that are coated on colored particles in the test strip. The mixture then migrates upward on the membrane chromatographically by capillary action and reacts with recombinant HIV antigen on the membrane in the test line region. If the specimen contains antibodies to HIV-1 and/or Subtype O, or HIV-2, one colored line will appear in the test line region; if the specimen contains antibodies to HIV-1 and/or Subtype O, and HIV-2, two colored lines will appear in the test line region. Both indicate a positive result. If the specimen does not contain HIV-1, Subtype O, and/or HIV-2 antibodies, no colored line will appear in the test line region indicating a negative result. To serve as a procedural control, a colored line will always appear in the control line region indicating that proper volume of specimen has been added and membrane wicking has occurred.
