What is Involved in Allergy Testing?

allergy testingIn our blogs, we always talk about how at CT Sinus Center we have the most up-to-date diagnostic tools for pinpointing the exact cause of your allergies. In today’s blog, we are going to discuss what is involved so that you know what to expect when you come in for your allergy testing appointment.

Let us begin by saying that we don’t jump into the actual testing. First, our staff will sit down with you and thoroughly discuss your medical history and symptoms. Next, before we start any type of test, we will explain to you what we’re going to do because our top priority — next to making you feel better — is making you feel at ease.

Once you are ready, we will begin the actual allergy testing process, which can involve a skin and/or blood test. Here are the different types with descriptions from Mayo Clinic:

Skin Prick Tests

  • May be called puncture or scratch test
  • The test is painless and barely penetrates the skin
  • Done on forearm (adult) and back (child)
  • Process: Site is cleaned with alcohol and marked, and then a drop of allergen extract is applied and pricked into the skin with a tiny needle
  • Histamine and Glycerin or saline are applied to site
  • After 15 minutes, doctor checks site for reaction
  • Can test up to 40 allergens at once, including pollen, mold, pet dander, dust mites and foods

Skin injection test

  • Done on forearm
  • Process: Small needle injects the allergen into skin
  • After 15 minutes, doctor checks site for reaction
  • Usually used to detect allergy to insect venom or penicillin

Patch test

  • Tests for contact dermatitis
  • Done on arm or back
  • Process: Allergen is applied to patch and then patch is placed on skin
  • After 48 hours, doctor checks site for reaction
  • Can test 20 to 30 allergens at once, including latex, medications, fragrances, preservatives, hair dyes, metals and resins

Blood test

According to the College of Allergy, Asthma and Immunology (ACAAI), a blood test is usually done if:

  • The patient is taking a medicine that can interfere with skin testing, but cannot be stopped for a few days
  • The patient suffers from a severe skin condition such as eczema or psoriasis
  • Testing with a strong allergen might cause an extra large positive reaction
  • A single needle stick for allergy blood testing may be better than several skin tests, especially for babies and very young children

Now that you know what to expect, schedule an appointment for allergy testing at CT Sinus Center and take the first step in finding permanent relief.
