ABSTRACT:
The invention relates to a heterogeneous immunoassay which is carried out using a multizoned test device. In particular, the invention involves the use of an inhibitor of a label which is used in the assay. The label which may be an enzyme, is attached to a receptor such as an antibody. The inhibitor is not acted upon by the label, but must be removed in order for a signal to be produced. Also described are test strips which can be used for the assay.
