Summary:A new immunoassay method for providing sensitive and rapid detection of ligands in body fluids utilizing colloidal gold labeled reagents and a matrix membrane strip having an immunologically active component immobilized therein. The sample and the fluid reagent having the colloidal gold labeled biologically active molecule is mixed and then brought into contact with one end of the membrane strip allowing flow upward through the membrane. The height of the visually observable color may be correlated to the presence of the ligand to be determined in the fluid sample.
