    "definition": "Delay in cutaneous immune reaction to specific antigens mediated not by antibodies but by cells. The delayed hypersensitivity test is an immune function test measuring the presence of activated T cells that recognize a specific antigen and is performed by injecting a small amount of the antigen into the skin. The area of the injection is examined 48-72 hours thereafter.",
