Overview of competitive ELISA method. In competitive ELISA, also referred to as inhibition ELISA, the concentration of the target antigen is determined by detection of signal interference. The target antigen in the sample competes with a labeled reference or standard for binding to a limited amount of antibodies immobilized on the plate.
