Introduction There are multiple Immunological techniques or tests used for starting and measuring an immune response (1). Antibodies and antigens found in our immune system is done by immunoassays (2). The majority of immunological tests are based on the adaptive immune system. Substances recognized by our immune system are antigens. Injections are done by a trained health care professional to test for an immune response. The antibodies work together to fight antigens. Immunologists can inject antigens into the body and observe the reactions. Out of the five antibodies, IgG and IgE are most common when testing hypersensitivities (3). Two tests that are commonly used today are the Coombs test, which deals with pregnant women’s Rh factor being the opposite of the fetus, and the Mantoux Tuberculin Skin Test, which tests for exposure or presence of tuberculosis.
Procedure 1 immunological science introduction Tuberculosis is considered a type IV hypersensitivity, or delayed cell-mediated reaction, and is tested by an injection through the skin. Sensitized T-cells make their way to the part of the skin where lymphokines (proteins that signal between cells) accumulate (4). The lymphokines create a raised, red swelled area by vasodilation, fibrin deposition (protein used during blood clotting) (5), edema, and the gathering of cells that cause inflammation (6). The results for tuberculosis are delayed, but after a day the presence of antigen can be found. The test is checking for…
