What is Allergy Skin Testing?
Allergy skin testing in NJ and NY allows us to diagnose environmental, food, bee sting or medication allergies by observing if there are signs of a histamine release. Histamine, when released from the allergy cells in the skin known as mast cells, will cause a “wheal and flare” reaction. This reaction is a small hive, which is raised, red and itchy. Histamine causes this reaction by binding to histamine receptors in the skin.
Types of Allergy Skin Testing in New Jersey and New York
Prick-Puncture: This test is performed by placing a small amount of an allergen in a liquid form on your skin. The skin is pricked so the allergen goes under the skin’s surface. Typically performed on the forearm and back. The test is ready after approximately 10 minutes. A positive test is when there is a “wheal and flare” or “swelling and redness.” This is indicative of histamine release, which occurs when one is allergic to an allergen. One must be off all antihistamines and H2 Blockers (stomach acid reducers) for at least 3 days prior to any allergy skin testing.
Intradermal Testing in NJ & NY: This is a more in-depth allergy skin test. It is performed using a small needle and injecting a small amount of the allergen under the skin. One must be off all antihistamines and H2 Blockers (stomach acid reducers) for at least 3 days prior to any allergy skin testing.
Who Can Take an Allergy Skin Test?
An allergy skin test in New Jersey and New York can be taken by those who suspect they may have allergies to certain substances such as pollen, pet dander, mold, dust mites, certain foods, or insect venom. Allergy skin testing is often recommended for:
- People experiencing allergy symptoms.
- Individuals who want to confirm their allergic reactions.
- People with a family history of allergies, since they are often at a higher risk.
- Patients experiencing unexplained or recurrent symptoms.
It’s important to consult with an allergist to determine if an allergy skin test is appropriate for your specific situation. Some situations where allergy skin testing may not be recommended would be, for example, when individuals have certain skin conditions, such as severe eczema or psoriasis. They may not be suitable candidates for skin testing.

What to Expect From an Allergy Skin Test in NJ and NY
An allergy skin test is a common diagnostic procedure used to determine a person’s allergic reactions to specific substances or allergens. Here’s a step-by-step overview of what typically happens during an allergy skin test:
Consultation and Preparation
You’ll discuss your medical history and allergies with your allergist. They may provide instructions on medication and dietary restrictions.
Allergen Selection
Based on your history, your provider selects allergens for testing, such as pollen, dust mites, or foods.
Skin Prick Test or Intradermal Skin Testing
In the skin prick test, the allergen extracts are applied to your forearm or back, and your skin is pricked to allow the allergens to enter. On the other hand, if the allergist decides to perform an intradermal skin test, this will involve the injection of a small amount of the suspected allergen under the surface of the skin
Waiting Period
You’ll wait for 10-15 minutes without scratching or touching the tested area.
Results Discussion
The provider checks for raised bumps (wheals) and redness, indicating allergic reactions. Your healthcare provider discusses which allergens triggered reactions and their severity, guiding your allergy management plan.
Note: Allergy skin tests are generally safe and well-tolerated but there is a minimal risk of experiencing an allergic reaction during the test. Immediate medical attention will be provided if needed.
Allergy Skin Testing FAQs
Where on the body do you place skin tests?
Skin tests for allergies are typically performed on the forearm or back. The allergist will clean the area to be tested and then apply a small amount of each allergen extract onto the skin. They may use a specialized device to prick the skin (called a skin prick test or allergy scratch test) or inject a tiny amount of allergen under the skin (called an intradermal test).
How to read allergy skin test results?
Reading allergy skin test results involves observing the appearance and size of skin reactions to specific allergens. These reactions usually manifest as raised, red bumps surrounded by redness on the skin. A positive reaction indicates sensitivity to the allergen, while a negative reaction suggests no sensitivity. Our allergists are ready to assist you in interpreting your allergy skin test results today!
How long does a skin allergy test take?
The duration of skin testing can vary depending on the number of allergens being tested and the specific testing method used, but usually, a skin prick test or allergy scratch test takes about 10-15 minutes. Similar duration for intradermal tests.
Do allergy tests hurt?
Skin testing is generally well-tolerated and is not typically painful.

Are skin allergy tests accurate?
Overall, when performed and interpreted correctly, skin allergy tests are valuable tools for diagnosing allergies and choosing treatment strategies. However, they should always involve a comprehensive clinical evaluation for the most accurate diagnosis and management of allergic conditions.
