A very sensitive, specific laboratory test (assay) that uses radiolabeled and unlabeled substances in an immunological (antibody-antigen) reaction.
Not sensitive to X-rays and other forms of radiant energy. For example, if a tumor is radioinsensitive, it cannot be successfully attacked by using radiation therapy. The opposite of radioinsensitive is radiosensitive.
