Immunoassays are reliable and widely used in toxicology for the detection and quantification of specific toxins. They employ antibodies that specifically bind to the target toxin, allowing for rapid and accurate detection. Immunoassays are used in various settings, including clinical, environmental, and food safety applications. Their high specificity and sensitivity make them valuable tools in toxicological diagnostics, although they may require confirmation by more definitive methods like GC-MS.
