Human immunodeficiency virus (HIV) is the cause of AIDS disease. It is a sexually transmitted infection that currently has no cure. Most people only start displaying symptoms very late in the disease process. Therefore, it is important to get tested regularly. There are 2 main strains of HIV which produce the same clinical outcome. The HIV 1/2 antigen/antibody is a 4th generation combination assay test that is used as the screening test to detect either HIV virus or antibodies to the virus in the blood. This HIV lab test is a good method for screening even if there is no symptoms as it is good at detecting HIV.
