A direct enzyme-linked immunosorbent assay (ELISA) test on a patient's sample is shown below. Development of a strong (dark) color reaction would indicate: 1 Antibody is adsorbed to well. 2 Patient sample is added; complementary antigen binds to antibody. 3 Enzyme-linked antibody specific 4 Enzyme's substrate () is added, for test antigen is added and binds and reaction produces a product that causes a visible color change (O). to antigen, forming sandwich. A low concentration of a specific antigen in the patient's sample O A high concentration of a specific enzyme in the patient's sample The patient's antibody is specific for the enzyme's substrate O A high concentration of a specific antigen in the patient's sample A high concentration of a specific antibody (against the test antigen) in the patient's sample
