HIV - P24
When the HIV virus invades the human body, it stimulates the immune system to produce specific HIV antigens. HIV antibody testing, also known as serological testing, is a routine method for assessing the presence of HIV antibodies in an individual's blood. Commonly used HIV antibody testing techniques include Enzyme-Linked Immunosorbent Assay (ELISA), chemiluminescent immunoassay, immunofluorescence assay, and immunochromatographic tests.
