PCT No. PCT/IB94/00039 Sec. 371 Date Oct. 23, 1995 Sec. 102(e) Date Oct. 23, 1995 PCT Filed Feb. 25, 1994 PCT Pub. No. WO94/20853 PCT Pub. Date Sep. 15, 1994An immunochemical method is provided for the detection and determination of an analyte. The zeta potential of a latex-particle loaded with an immunologically active substance is measured before and after bringing the loaded latex-particle into contact with an analyte. The difference in zeta potential is correlated with changes of zeta potential for known concentrations of the analyte in order to determine the presence and amount of the analyte.
