Which of the following is NOT the most commonly used treatment for diagnosing type 1 hypersensitivity? Correct Answer Immunotherapies

There is actually no permanent cure for treating type 1 hypersensitivity reactions. The treatments are done so as to maintain its control only. Some of the most commonly used methods and medications are: 1) mast cell stabilizers as mast cell (a type of white blood cell) plays a major role in allergic reactions, the aim of these drugs is to block the action of mast cells. 2) steroids which can directly be applied on site of involvement in case of skin allergies or can be consumed. 3) antihistamines can also be taken by mouth or if it is in the form of cream/oil, it can be applied directly on skin (in case of skin allergies). On the other hand, immunotherapy is not commonly used for maintaining the control of the spread of type 1 hypersensitivity reactions.
