- Use this information to answer the question. Human Immunodeficiency viruses, Types 1 and 2 (HIV 1,2) Antibody testing (1985) and NAT (1999) Blood donation screening for HIV-1, the causative agent of AIDS began with antibody testing in 1985. Many improvements in testing have occurred including adding the detection of a second HIV agent (HIV-2 in 1992). A chemiluminescent immunoassay (ChLIA) is used for the qualitative detection of antibodies to HIV-1 and HIV-2. A duplex nucleic acid test (NAT) was introduced for HIV-1/HCV RNA detection in 1999, and updated to include the detection of HBV DNA in 2009 (see above). The next version of NAT will include HIV-2 RNA detection (to be implemented in 2020). Donors who test antibody reactive are further evaluated by additional tests to confirm the presence of HIV antibody and to differentiate HIV-1 from HIV-2 antibodies. Tests for this purpose have included a HIV western blot, an HIV-2 enzyme-linked immunoassay and an HIV-1 and HIV-2 rapid test…arrow_forwardShould we spread out the inoculation schedule OF HIV to prevent confusion of a young person?
