Environmental Allergy Testing
The skin prick, or scratch test, is one of the common tests used to identify specific allergens that may be contributing IgE/immediate allergy symptoms. Diluted allergens are introduced to the surface layer of skin with an applicator. After the allergens are applied, the test site is checked after 15 minutes for redness and or the development of a wheal. Based on the results of the allergy test, immunotherapy may be used to help desensitize the allergic reactions.
What is allergy testing indicated for?
- Seasonal allergies/hay fever
- Year-round environmental allergies
- Asthma, atopic dermatitis
- Chronic sinusitis
- Other immune and respiratory illnesses
What allergens can we test?
Common household allergens, as well as the prevalent common outdoor pollens in North America, including:
- Cat Dander Mix
- Dog Dander Mix
- Dust Mite Mix: Dermatophagoides Pteronyssinus, Dermatophagoides Farinae
- Mould Mix (4): Alternaria, Cladosporium, Aspergillus Fumigatus, Penicillium
- Grass Mix (5): June, Orchard, Sweet Vernal, Timothy, Red Top
- Ragweed Mix: Short and Tall
- Tree Mix (10): Alder, Birch, Oak, Poplar, Elm, Maple, Hickory, Sycamore, Ash, Beech
- Weed Mix (4): Cocklebur, Pigweed, English Plantain, Lamb’s Quarter
Prepare for the Test
No strenuous physical activity immediately before the test. Vigorous physical exercise could potentially increase the risk of an allergic reaction during the testing. It’s best to delay exercise until at least 3 hours after your testing. Discontinue antihistamines for 7 days prior to testing.
Treatment Option: SLIT
’SLIT’ therapy (sublingual immunotherapy) is an allergy treatment using small amounts of allergens taken orally to desensitize your immune reaction to those allergens. Research over the past 20 years has shown that SLIT is safe and effective for treating allergic rhinitis, as well as asthma and atopic dermatitis caused by allergies to dust mites, grass, ragweed, cat dander, and tree pollens.
