Zusammenfassung:A new immunoassay method for providing sensitive and rapid detection of ligands in body fluids utilizing colloidal gold labeled reagents and a matrix membrane having an immunologically active component therein. All liquid materials brought into contact with one side of the membrane flow through the membrane into an absorbent material in physical and fluid communication with the other side of the membrane. Reactions may be visually detected and in the case of hCG, a sensitivity of 50 mIU or less may be had within a total assay and manipulation time of one and a-half minutes.
