antibody detection

**antibody detection**

Antibody detection refers to the process of identifying specific antibodies in a sample, typically blood or serum, to determine if an individual has been exposed to a particular antigen, such as a virus, bacteria, or other pathogen. This technique is widely used in diagnostic testing, immunology research, and vaccine development to assess immune response and monitor infections or diseases. Common methods of antibody detection include ELISA (enzyme-linked immunosorbent assay), Western blot, and immunofluorescence assays. Understanding antibody presence and concentration helps guide clinical decisions and epidemiological studies.
