Barbituric acid antigens are prepared by coupling 5- or 5,5-substituted barbituric acid to immunogenic carrier materials. In preferred embodiments, proteins are used as the carrier materials and the coupling is effected by an amide linkage between the 5-substituent of the barbituric acid and a carboxyl or amino group of the protein. The resulting antigens produce immunological effects when injected into host animals, including the formation of antibodies specific for 5- and 5,5-substituted barbituric acids. These specific antibodies are useful in bioanalytical techniques for the assay of barbituric acids in biological fluids.
