How Do Doctors Test and Diagnose Allergies?
There are several steps for diagnosing an allergy that a doctor may perform. Some of these steps include skin testing, taking a medical history, questioning of symptoms, physical examination, allergy tests, prick tests and intra-dermal needle tests.
The first thing the doctor will do is take your medical history. By doing this they ask the patient if they have any family history of allergies to specific substances. This helps them narrow down their list of appropriate tests to be performed on the person.
Skin tests are another form of testing doctors use to diagnose allergies. The best thing about them is that they are minimally invasive and very easy to conduct. There are two methods of performing a skin test for allergy, the prick test, and the intra-dermal needle test.
In the prick test, the doctor takes the smallest quantity of a material that could possibly be an allergen and pricks it on your skin. The intra-dermal needle test consists of taking an intra-dermal needle and using it to inject a small amount of the allergen under the skin.
