Dandelion Allergy Skin Testing
Find out what may be triggering your allergy symptoms.
Skin testing is a quick and commonly used way to help identify allergies to environmental allergens, foods, insect venom and some medications.
What is allergy skin testing?
Allergy skin testing helps determine whether your immune system is sensitive to specific allergens.
A very small amount of each allergen is placed on or just under the skin. The area is then watched for a small raised, itchy bump similar to a mosquito bite.
Skin test results are interpreted together with your symptoms and medical history. A positive test by itself does not always mean that an allergen is actually causing your symptoms.
What can we test for?
Depending on your symptoms, testing may include:
- Trees, grasses and weeds
- Dust mites
- Mould
- Cats and dogs
- Foods
- Insect venom
- Certain medications
Your allergist will decide which allergens are appropriate to test.
What happens during the test?
We review your symptoms
Your allergist reviews your medical history, symptoms and possible exposures.
Small amounts of allergen are applied
Drops containing selected allergens are placed on the skin, usually the forearm or back.
The skin is gently pricked
A small disposable testing device allows the allergen to enter the surface of the skin.
We wait for a reaction
The test is usually read after about 15 to 20 minutes.
Your allergist explains the results
Your results are combined with your history to determine whether an allergy is likely.
Does skin testing hurt?
Most patients describe it as mildly uncomfortable rather than painful.
If you react to an allergen, the area may become itchy for a short period.
Serious reactions to skin testing are rare, which is why testing is performed in a medical setting.
How should I prepare?
Some antihistamines can interfere with allergy testing.
Do not stop any medication unless you have been instructed to do so by the clinic.
We will tell you which medications, if any, need to be stopped before your appointment.
Frequently asked questions
Can children have skin testing?
Yes. Allergy skin testing can be performed in children when clinically appropriate.
Does a positive test mean I definitely have an allergy?
No. Testing shows sensitization. Your allergist must compare the result with your symptoms and history.
How long does the appointment take?
The testing itself is generally quick, although additional time is required for assessment and discussing your results.
