Hiv Test Kit

Principle

The HIV 1/2/O Tri-line Human Immunodeficiency Virus 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 HIV antigen-coated 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 the proper volume of specimen has been added and membrane wicking has occurred.
