ABSTRACT:
A method and device for testing for the presence of substances such as drugs in body fluids while simultaneously positively identifying the test subject. The device comprises an absorbent pad and a membrane mounted to the absorbent pad containing a plurality of separated areas provided with different immobilized ligand having a specific receptor site for capture or rejection of specific antigens produced by different predetermined drugs. The method of testing comprises the steps of: (a) obtaining a quantity of body fluid in a container, (b) adding an antibody to the body fluid to form a mixed solution, (c) placing the mixed solution on a membrane and absorbent pad device and immobilized ligands, (d) covering the finger with a thin film of labelled antibody and (e) placing the finger on the membrane containing immobilized ligand specifically selected to bind to labelled antibody presenting the fingerprint of the test subject, the presence or absense of substances being tested for in the body fluid so that solution is deposited from the finger on the membrane indicating presence or absence of the substance.
