Hello!

This response is typical of a type I hypersensivity reaction.

Explanation:

The Mantoux test, also known as the Mantoux screening test, is a procedure to test for exposure to the tuberculosis bacillus and its diagnosis. It is one of the most important tuberculin skin tests in which a dose is injected intradermally to the patient.

Atopic dermatitis is a type I hypersensitivity reaction which results in itchy, cracked and red skin on the site of injection. The reaction in this example is a clear reaction to this type of hypersensitivity.
