Allergists often say that history is the biggest determinant in diagnosing a patient’s allergies. However, specific allergy testing can also aid greatly in making the diagnosis There are three tests commonly used that look for allergies in different ways. For skin testing, a small syringe is filled with an individual allergen and injected under the dermal layer of the skin. Skin prick testing is done through a device that can deliver one or multiple antigens simultaneously into the skin Blood testing for allergies is identical to any other blood test, simply drawing a vial of blood from a ready vein to detect food and inhalant allergies. After testing, precise, individually-tailored allergy drops can be prescribed to treat the root cause of the allergy. Find more about allergy testing on our blog!
