A patch test relies on the principle of a type IV hypersensitivity reaction.. The first step in becoming allergic is sensitization.

[1] It was long conjectured by engineers that passing the patch test is sufficient for the convergence of the finite element, that is, to ensure that the solutions from the finite element method converge to the exact solution of the partial differential equation as the finite element mesh is refined. However, this is not the case, and the patch ...
A patch test (contact delayed hypersensitivity allergy test) [17] is a commonly used examination to determine the exact cause of an allergic contact dermatitis. According to the American Academy of Allergy, Asthma, and Immunology, "patch testing is the gold standard for contact allergen identification".
