Enzyme-Linked Immunosorbent Assay Immunoassay (ELISA)

ELISA is a well-established immunodiagnostic technique used for the sensitive and specific detection of antigens or antibodies in biological samples. The assay is based on antigen–antibody binding on a solid phase, followed by enzyme-mediated signal generation that enables quantitative analysis. Using enzyme-labelled antibodies and chromogenic substrates, ELISA delivers consistent and reproducible results across a wide range of clinical and research applications. Its proven analytical performance makes ELISA a trusted platform in various clinical applications like diagnosis of hormonal disorders, autoimmune conditions, cardiac disorders, etc.
