Answer 1

ELISA (Enzyme-Linked Immunosorbent Assay) is a widely used diagnostic test that detects HIV antibodies in blood samples. It serves as the first screening test for HIV infection. A positive ELISA result is typically followed by a confirmatory test such as Western Blot to rule out false positives and ensure accurate diagnosis.
