Immediate ligand detection assay

A competitive immediate ligand detection assay process, comprising:

• combining together in an aqueous medium:
• a sample to be assayed containing an unknown amount of cold ligand reactant;
• a known quantity of radiolabeled ligand reactant;
• and
• a plurality of support particles having fluorescer integrated therewith capable of emitting photons when activated by the radiation energy emitted by the radiolabeled ligand and having ligand attached to the outer surface thereto, said ligand capable of indiscriminately binding with both said cold and radiolabeled ligand reactant whereupon the binding of the ligand with the radiolabeled ligand reactant positions the radiolabeled ligand reactant close enough to the support particles to activate the fluorescer to emit photons through the aqueous medium, whereas the unbound radiolabeled ligand reactant is generally positioned too far away from the support particles to enable the radioactive energy emitted thereby to activate the fluorescer;
• and
• measuring the photons emitted by the fluorescer with the entire quantities of cold ligand reactant containing sample, radiolabeled ligand reactant and support particles remaining combined together in the aqueous medium.
