The HIV Antigen/Antibody Combo Test is a screening test for Human Immunodeficiency Virus (HIV) infection. It detects both HIV antigens (p24) and antibodies to HIV-1 and HIV-2. This test is more sensitive than traditional antibody-only tests and can detect HIV infection earlier, potentially as soon as 2-3 weeks after exposure. It's crucial for early diagnosis, allowing prompt treatment initiation and prevention of transmission. The test is recommended for routine screening of adults and adolescents, and is particularly important for individuals at higher risk of HIV exposure.
A ‘low’ or ‘non-reactive’ result on the HIV Ag/Ab Combo Test typically means that no HIV antigens or antibodies were detected in the blood sample. This generally indicates that the person is not infected with HIV. However, it’s important to note that there’s a ‘window period’ during which a person may be infected but not yet produce detectable levels of antigens or antibodies. If there’s recent potential exposure, retesting may be recommended.
A ‘high’ or ‘reactive’ result on the HIV Ag/Ab Combo Test suggests the presence of HIV antigens and/or antibodies in the blood sample. This indicates a potential HIV infection. However, a reactive result is not a definitive diagnosis of HIV. Confirmatory testing, such as a Western blot or HIV RNA test, is required to establish a diagnosis. If confirmed positive, it means the individual is infected with HIV and should be referred for medical care and counseling.
