Note
This fourth-generation screen test is for the simultaneous qualitative detection of Human Immunodeficiency Virus Type 1 (HIV-1) p24 antigen and antibodies to HIV Type 1 (HIV-1 groups M and O) and HIV Type 2 (HIV-2), Results of the screen cannot be used to distinguish between the presence of HIV-1 p24 antigen, HIV-1 antibody, or HIV-2 antibody.
If the HIV-1,2 Combo Antigen/Antibodies screen is repeatedly reactive, then the Human Immunodeficiency Virus Type 1 (HIV-1) Antibody Confirmation by Western Blot will be added. Additional charges apply.
