Human Immunodeficiency Virus (HIV) Combo Antigen/Antibody (HIV-1/O/2) by CIA with Reflex to HIV-1/HIV-2 Antibody Differentiation, Supplemental
Also known as: HIVAGABGE
Use
This 4th generation test screens for HIV-1 p24 antigen and antibodies to HIV-1 (groups M and O) and HIV-2. It is used for detecting HIV infection, though it does not constitute the full 2014 CDC recommended algorithm for HIV diagnosis. Results that are repeatedly reactive will reflex to an HIV-1/HIV-2 antibody differentiation test, which helps in distinguishing between HIV-1 and HIV-2 antibodies as recommended by the CDC and adopted by the CLSI.
Special Instructions
Not provided.
Limitations
The test cannot distinguish between the presence of HIV-1 p24 antigen, HIV-1 antibody, or HIV-2 antibody. It should not be utilized for screening blood donors or products derived from human tissues and cells. Reactivity might be influenced by particulate material, hemolysis, or heat inactivation of specimens which could lead to assay rejection.
