ABSTRACT:
A method for the qualitative or quantitative determination of an analyte in a test sample wherein a labelled reagent is caused to be immobilized in bound form on a solid phase to provide an indication of the presence or quantity of the analyte in the same is disclosed and is characterized in that the labelled reagent comprises a gold sol bound to a substance capable of specifically binding to said analyte or to a specific binding partner therefor, at least 75% by weight of the gold particles of the gold sol having a mean diameter of less than 5 nanometers.
