1. Apparatus for fluorescence immunoassays relying on an immunochemical complex formed by reaction between a first constituent of said immunochemical complex and a second constituent of said immunochemical complex, which second constituent includes a fluorescent tag, said apparatus comprising in combination:

  • an optical fiber transmissive to radiation which can excite fluorescene of said fluorescent tag and transmissive to fluorescent radiation from said fluorescent tag; and

    a plurality of said first constituents so attached to at least a portion of the side surface of said optical fiber as to leave substantially unaffected the reactivity of said first constituent to form said immunochemical complex, with at least a part of said first constituent being complexed with a predetermined amount of said second constituent.
