When it comes to finding relief from allergy symptoms, identifying the root cause of your discomfort is essential. For many people undergoing allergy testing is the first step toward better health. But with several testing methods available, how do you know which one is right for you? In this blog, we'll break down the most common types of allergies testing and help you determine which test might be the best fit for your needs.

Understanding Allergy Testing Options

Allergies can cause a wide range of symptoms, from sneezing and itching to more severe reactions such as asthma or anaphylaxis. To properly diagnose the cause of your symptoms, healthcare providers offer a variety of testing options. Here's a closer look at the main types of allergy tests:

What is the Skin Prick Test?

The skin prick test is one of the most common methods used for diagnosing allergies. During this test, small amounts of common allergens (such as pollen, pet dander, or certain foods) are placed on the skin, usually on your arm or back. A tiny, painless prick allows the allergen to penetrate the skin's surface. If you're allergic to a substance, a small red bump will appear at the test site within 15-20 minutes.

Pros:

  • Quick results (within minutes)
  • Tests multiple allergens at once
  • Minimally invasive

Cons:

  • Not suitable for patients with severe skin conditions
  • May cause mild discomfort at the test sites
  • Intradermal Testing

What is Intradermal Testing?

Intradermal testing involves injecting a small amount of allergen just beneath the skin. This test is more sensitive than the skin prick test and is often used when the results of the prick test are inconclusive. It's also commonly used to diagnose drug allergies and insect venom allergies.

Pros:

  • Highly sensitive test
  • Useful for identifying drug and venom allergies

Cons:

  • Slightly more invasive than a skin prick test
  • Higher chance of a false-positive result
  • Blood Test (IgE Testing)

What is Blood Testing for Allergies?

A blood test, or IgE (Immunoglobulin E) test, measures the amount of allergies-causing antibodies in your blood. This method is often used when skin tests are not possible, such as for patients with certain skin conditions, or for those who are on medications that could interfere with skin testing results.

Pros:

  • Only requires a blood sample
  • Can be performed regardless of medication use
  • Useful for diagnosing a wide range of allergies

Cons:

  • Takes longer to get results (days vs. minutes)
  • Less sensitive than skin testing
  • Choosing the Right Test for You

Deciding which allergy test is right for you depends on several factors, including the type of allergy you're experiencing, your medical history, and personal preferences. If you’re unsure, consulting with an allergy specialist can help guide your decision.

We hope that you and your family are safe and healthy. Given the following: many of our patients have underlying conditions that could potentially make infection with COVID-19 more severe in light of the fact that the ongoing novel Coronavirus pandemic is officially now local, to ensure the clinic can remain open to best serve the needs for ALL of our allergy and asthma patients, we have implemented the following: If you have a cough or fever, DO NOT come to the office. Call ahead first . We may be able to schedule a Tele-Visit to accommodate you. This is to protect all of our patients in the waiting room who are not ill. We are unable to test for COVID-19. Currently this must be done at our local health department. We have enhanced our already robust office cleaning protocols, cleaning all contact surfaces frequently with powerful antiseptic products. Patients with cough (it is asthma season) are provided mask Before entering the clinic and will be directly taken to an exam room to isolate from the general waiting room population We encourage all of our patients to follow the recommendations of the CDC and WHO to limit exposure: CDC: https://www.cdc.gov/coronavirus/2019-ncov/index.html WHO: Coronavirus Remember also that the flu is still circulating and if you haven’t had your flu shot, it’s time to get it now. As of today a fever is still likely to NOT be COVID-19, but that may change rapidly. If you’ve been taking your asthma medication less than regularly, it is now time to religiously take them daily as prescribed. If you have questions about how to use them please contact us. If you need refills please let your pharmacy know, they will contact us. Working together, we can slow the spread of this virus and minimize its impact. It is spring and allergy season is here. COVID-19 doesn’t change that. My office is here to continue to manage all of the usual symptoms you may experience. We don’t want anyone to fall behind on allergy shots if at all possible. Hopefully this pandemic will pass in a few months, but another allergy season is always just around the corner. Let us know if we can help and take care of yourselves and your families! All of our best, Dr Haden and all of the staff at Haden Allergy
