An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. For instance antigens include microorganisms and chemicals. Antibodies may occur when the immune system mistakenly considers healthy tissue a harmful substance. This is called a disorder. Each type of antibody is unique and defends the body against one specific type of antigen.
