Identifying the substances that trigger allergy symptoms is the first step in preventing allergic reactions. Whether you’re experiencing itching, sneezing, rashes or any other symptom, your Atlanta allergist may recommend allergy testing for a precise diagnosis. The most common allergy testing option is skin prick testing – a procedure that can be handled in a single visit. Before undergoing this test, it may be helpful to understand what to expect during a visit.
What Is Skin Prick Testing?
A skin prick test (sometimes called a scratch test) involves placing drops of an allergenic solution on the forearm or back. Next, the skin’s surface is gently punctured with a small needle, allowing the allergen to enter the skin. When the skin is exposed to a substance the body sees as a threat, IgE antibodies on the surface of mast cells trigger the release of histamine and other substances, leading to inflammation at the puncture point.
What to Expect During a Skin Prick Test Procedure
If you notice symptoms such as runny nose, sneezing, coughing, itching, swelling or breathing difficulties after exposure to substances like pollen, dust, mold, pet dander or specific foods, you should see an allergist for treatment.
- Your arm or back is first cleaned, then patches are applied.
- Each drop of potential allergen is placed within its specific area of the patch.
- The skin underneath each drop will be lightly scratched or pricked.
- If allergic to any substance, a reaction should occur within 15–20 minutes
- A raised bump or redness indicates a response to an allergen.
Preceded by an assessment of your allergy symptoms and medical history, your allergist uses the skin prick test results to deliver a sound diagnosis. (Note that you may feel mild itching or discomfort for a short period after the skin prick test.)
How to Prepare for Allergy Testing
Allergists often advise their patients to stop taking antihistamines for around three to seven days before the test. Tell your allergist about any other medications you’re taking, as they might interfere with test results. Also, it can be helpful to wear loose clothing for easy access to the testing area.
What Happens After a Skin Prick Test?
After the skin prick test is complete and your allergist has identified the precise allergen or allergens responsible for triggering your reaction, you’ll be advised on the best available allergy treatment options. Allergy desensitization through allergy shots or oral immunotherapy may be the preferred option for many patients. These treatments require a commitment of several months, but they remain the most effective ways to achieve long-term relief from severe allergies.
