moodus, kus aine kontsentratsiooni või hulga määramiseks kasutatakse antigeen-antikeha reaktsiooni (nt. radioimmuunanalüüs)
a large group of procedures which exploit the ability of antibodies to recognise specific antigens
Good to know
Either the antibody or antigen can be identified with radioactive, fluorescent or chemiluminescent labels and often the reaction is linked to an enzyme system to amplify or modify the effect
The routine analytical procedures authorized for detecting residues of substances having a hormonal or a thyrostatic action shall be the following:
- immunoassay,
- thin-layer chromatography,
- liquid chromatography,
- gas chromatography,
- mass spectrometry,
- spectrometry, or any other method which fulfils comparable criteria to those laid down for related methods in the Annex.
