Disclosed herein is an improved method for the detection and determination of haptens by contacting a sample of body fluid with a hapten-enzyme conjugate and a specific binding protein (i.e., antibody) for the hapten. The improvement is characterized in that the nature of the couple in the hapten-protein conjugate used to generate the specific binding protein differs from the couple in the hapten-enzyme conjugate. Also disclosed is a testpack containing the components required in the test method. |
