Skin Testing is the most accurate diagnostic test used by a trained allergist/immunologist. An allergist typically conducts this test on the arms or upper back of the patient. The skin is lightly scratched on the surface with a tiny amount of the allergen on the tip of a small instrument, similar to a plastic toothpick.
If you are allergic to a substance, a small mosquito bite-like bump will appear which allows the allergist to determine your specific allergy profile. A major pro of this test is that results can happen within 15 to 20 minutes. We will test for allergies to foods, dust mites, cats, dogs, feathers, mice, cockroach, horses, and the most prevalent trees, molds, weeds and grasses in the area.
They also have the advantage of being less invasive than blood tests and provide a good alternative for children or patients who may have an aversion to needles. They also cause little pain or inconvenience for a patient and can be conducted on an outpatient basis.
