A test or technique in which one or other component of an immunological reaction is made fluorescent by coupling with a fluorochrome such as fluorescein, phycoerythrin or rhodamine so that the occurrence of the reaction can be detected as a fluorescing antigen-antibody complex. Used in microscopy to localize small amounts of antigen or specific antibody.
