A laboratory test that uses antibodies to test for certain antigens in a sample of cells. The antibody is usually linked to a radioactive substance or a dye that causes the cells to light up under a microscope. Immunocytochemistry is used to help diagnose diseases, such as cancer. It may also be used to help tell the difference between different types of cancer.
