Free analytes in samples containing free analytes and receptorbound analytes are determined by absorbing at least a portion of free analyte from the sample with insolubilized receptor or receptor which is then made insoluble, washing the insoluble receptor, adding labelled sample analyte or labelled sample analyte receptor, incubating, washing the insoluble phase free of the soluble phase and determining the label in either phase. The method solves a long standing need in the assay of free thyroid hormones.
