Immunoassay
An immunoassay is a laboratory technique used to detect and measure specific proteins or other substances in a sample, such as blood or urine. It relies on the principle of antigen-antibody interactions, where antibodies bind to their target antigens, allowing for the identification and quantification of various biomolecules.
These tests are widely used in clinical diagnostics, research, and drug development. Common types of immunoassays include enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), and lateral flow assays. They are valuable tools for diagnosing diseases, monitoring health conditions, and ensuring the safety of pharmaceuticals.
