4th generation ELISA
HIV - infectious diseases - safe blood banking - serology
The apDia HIV Ag/Ab assay (Ref. 790001 and 790005) is a 4th generation solid phase Enzyme-Linked ImmunoSorbent Assay using a mixture of antigens and antibodies for the in vitro diagnostic screening in human serum or plasma of antibodies to HIV-1, HIV-2 and HIV-P24 antigen. Acquired immune deficiency syndrome (AIDS) is a set of symptoms resulting from the incapacitation of the human immune system caused by the Human Immunodeficiency Virus (HIV). HIV infection may progress to a symptomatic phase that is characterized by opportunistic infections and that may cause death.
The etiological agent of AIDS, HIV, targets specific types of T cells causing Lymphopenia and affecting T cell mediated immunity.
HIV is a member of a retrovirus family with two sub-families: HIV-1 and HIV-2. HIV-1 is more virulent and transmittable than HIV-2. HIV-1 is the cause of HIV infections globally, whereas HIV-2 is found predominantly in the countries of West Africa. As serological cross-reaction between HIV-1 and HIV-2 is highly variable and dependent on the tested sample, antigens for the specific detection of both HIV-1 and HIV-2 are included in the assay.
HIV is transmitted through sexual contact with infected persons, sharing needles and syringes with infected people and transfusion of contaminated blood.
Enzyme-Linked ImmunoSorbent Assays (such as the apDia HIV Ag/Ab ELISA 4th gen) are recommended for screening human blood and plasma for the presence of anti-HIV antibodies and HIV-P24 antigen.
