Caption: AIDS test: Positive (yellow) and negative (clear) results for presence of antibodies to Human Immunodeficiency virus (HIV), the AIDS virus, displayed on an ELISA (enzyme-linked immunosorbent assay) test plate. The ELISA test involves adding a patient's blood serum to lysed (burst) T- lymphocytes infected with HIV, causing any viral antibodies in serum to bind to viral antigens from the T-cell. This operation is performed in one well on the test plate, and after washing, labelled antihuman immunoglobulin is added which provokes a colour change if HIV antibodies are present.
