Allergy Testing


Allergy testing is a way to find out if you are allergic to something, called an allergen. Common allergens include pet dander, pollen, insect bites or stings, and certain foods, such as peanuts. Your healthcare provider will use an allergy test to check your body's response to the allergen. During the test, he or she will watch for small skin reactions that show you are probably allergic. He or she will also watch for a rare but serious reaction that needs immediate treatment. You will need to watch for a reaction that develops later, after you are home.


Call 911 for any of the following:

  • You have any of the following signs or symptoms of anaphylaxis:
    Signs and Symptoms of Anaphylaxis
    • Itching, a rash, hives that spread over your body
    • Trouble breathing, swelling in your mouth or throat, or wheezing
    • Feeling you are going to faint

Contact your healthcare provider if:

  • You have new or worsening rashes, hives, or itching.
  • You have an upset stomach or are vomiting.
  • You have stomach cramps or diarrhea.
  • You have questions or concerns about your condition or care.


  • Antihistamines may be needed if you have a reaction to your allergy test.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your healthcare provider as directed:

You may need more tests, or treatment for an allergy. Your provider may also refer you to a specialist. Write down your questions so you remember to ask them during your visits.
