Immunochemical assay reagents comprising combinations of (A) a carboxyl-containing water-soluble mono-olefinic polymeric compound combined with a hapten or a chemically modified product thereof, or a hapten-supported latex resulting from the chemical linking of the hapten-bound polymeric compound to a polymeric latex, with (B) a hapten antibody, or a hapten antibody-supported carrier; and a method for immunochemically determining haptens using the assay reagent. The assay reagent is very stable and can be stored for an extended period of time without degradation. Transition from an agglutination inhibited pattern to an agglutinated pattern can be discerned clearly and rapidly with high sensitivity when using the assay reagent.
