Are there any side effects to allergy testing?

Any medical tests that are done involve some risk, this goes for all testing, not just allergy testing. However, the risks that are included with allergy skin tests is that, sometimes allergy symptoms may occur to the patient being tested during their initial test. The most common symptoms that are experienced during testing include itching and swelling of the skin in the area being tested. In very rare cases, a more serious reaction may occur. That is why all skin tests should only be done by a trained and experienced specialist or allergist. The risks that are associated with allergy blood tests is slight pain in the area that is being tested or minor bleeding at the needle mark. Also, very few people may faint during blood testing – this is due to a patient having a major fear of blood or needles.

Are there different methods to allergy testing?

There are different ways to test for allergies. It can be done as a skin test or as blood test. All allergy tests should be done under the direct guidance of an allergy specialist or allergist. These allergy doctors are highly-trained in the best practices and methods for all testing and the treatment of allergies. At Columbia Asthma & Allergy Clinic, our allergy specialists are ready to help you get relief from allergies today.

How does skin testing for allergies work?

There are two different types of skin testing. During the first type, a single drop of a suspected allergen is placed on the surface of the skin. This test is typically performed on the patient’s back or forearm. The specialist or allergist will test for many suspected allergens at the same time. If the patient is allergic to one of the tests, they will typically develop redness and swelling at the testing site.

In some cases, the allergy doctor or specialist will recommend a second type of test. In this test, a very small amount of the suspected allergen will be injected into the skin of the patient – typically done in the arm or forearm. Again, in this case several suspected allergens can be tested simultaneously.

How long will it take to get my skin test results back?

Skin testing is relatively quick. For both types of skin tests, any positive reactions will usually appear within the first 20 minutes of exposure to the allergen. In some cases, redness and swelling can occur several hours after the initial skin testing. The delayed reaction will usually disappear within 24 to 48 hours –but however, all reactions, no matter how slight they may be, should always be reported to the allergy doctor or nurse in a timely manner.

When will I require a blood test for allergy testing?

There are many different reasons why a blood test may be the recommended method for allergy testing. It’s very important for the patient to be very open and honest with their allergist to make sure that the right testing method is administered, and this is because it minimizes the risks. In the case that a patient will require a blood test as opposed to a skin test is often times because:

  • The patient is taking a specific medicine that can interfere with skin testing
  • The patient suffers from a skin condition like eczema or psoriasis
  • Testing with a strong allergen may cause an extra-large positive reaction and therefore allergists would like to avoid skin testing

To avoid any major reactions, talk to the allergists today about skin allergy testing. The allergy specialists at Columbia Asthma & Allergy Clinic in Longview, WA look forward to treating you and your loved ones.
