This immunoassay test uses a double antibody sandwich format. An antibody specific for staphylococcus aureus is sprayed in a line on the surface of a membrane comprising a “test line”. A second antibody reagent, also recognizing staphylococcus aureus and labeled with colloidal gold, is contained within a reagent pad upstream from the test line. As the sample moves from the filter pad, the antibody gold reagent specifically binds staphylococcus aureus and moves with the liquid sample into the test membrane. The sample passes through the test line where the immobilized second Staphylococcus aureus antibody captures the protein–antibody–gold complex, causing the formation of an antibody–protein “sandwich” and development of red color at the test line. Antibody–protein sandwiches are not formed in the absence of the staphylococcus aureus, resulting in no red color development at the test line.
