FIELD: medicine.
SUBSTANCE: test system for a semiquantitative immunochromatogrpahic assay consists of a plastic substrate a surface of which is overlapped with a membrane for a test piece, a membrane for a conjugate of gold nanoparticles and first specific monoclonal antibodies to a test compound, an analytic membrane, and a suction membrane. The analytic membrane comprises 2 to 10 discrete parallel test lines formed transversally by the pre-application of solutions of second specific monoclonal antibodies to the test compound; the antibody concentration increasing gradually from line to line.
EFFECT: enabled semiquantitative immunochromatogrpahic assay using no estimated measurement result equipment.
