An immunoassay dry test strip comprising a matrix having three zones wherein bypass of the second zone of test fluid containing analyte and label from the first zone is prevented by means to seal the second zone. The first zone contains a labeled-antibody composition having at least one specific analyte-antigen binding site; the second zone contains immobilized antigen composition that can bind specifically with an analyte-antigen binding site on said labeled-antibody; and the third zone, removed from said first and second zones, contains detection means for indicating the presence of the label of said labeled-antibody within said third zone. |
