There are three main types of skin tests: scratch/puncture/prick test (a few drops of allergen are pricked onto the skin surface), intradermal test (the allergen is injected under the skin) and patch test (a large patch with different allergens are applied on the skin).
A Patch Test diagnoses allergic reactions. A small patch of the suspected allergen is placed on the skin, and if the skin reacts, it's diagnosed as a allergic reaction.
Prick test is a dermatology skin tests usually done in order to identify allergies to pet dander, dust, pollen.Patch test,Skin end point titration are other tests used in dermatology.
Two types are used. A skin prick test, a small needle with a specific allergen on tip. An intradermal test: specific allergen injected under top layer of skin. Observe reactions.
Doctor will expose a person's skin with a variety of different potential things that could be an allergen. A certain amount of time will pass and then the doctor will look to see if the skin had changed in appearance.
