The human immunodeficiency viruses type 1 and type 2 (HIV 1+2) are the etiological agents of the acquired immunodeficiency syndrome (AIDS) and related conditions. HIV has been isolated from patients with AIDS, AIDS related complex (ARC) and from healthy individuals at high risk for AIDS. Infection with HIV is followed by an acute flu-like illness. This phase may remain unnoticed and the relationship to HIV infection may not be clear in many cases. The acute phase is typically followed by an asymptomatic carrier state, which progresses to clinical AIDS in about 50% of infected individuals within 10 years after seroconversion.

The Biorex Diagnostics HIV ELISA kits are an enzyme-linked immunosorbent assay (ELISA) intended for qualitative detection of antibodies to Human Immunodeficiency Viruses (HIV) type 1 (group M – O) or type 2 in human serum or plasma specimens. The assay can be utilized for screening of blood donors and/or as an aid in the diagnosis of clinical conditions related to infection with HIV-1 and /or HIV-2 – the etiological agents of the acquired immunodeficiency syndrome (AIDS). The Fortress HIV Anti HCV (4th Gen) kits are intended for use in screening blood donors and diagnosing patients related to the infection with hepatitis C virus.
