The Path to Allergy Relief: Testing
The only way to control allergies is to identify the specific allergen, or allergens, that cause a reaction from your immune system. Whether you have food allergies or a dog and cat pet dander allergy, we’re here to help you find allergy relief — beginning with an accurate diagnosis.
During your first visit, we’ll discuss your medical history, current allergy symptoms and any medications or treatments you’ve already tried. We will then decide if allergy testing is needed. With this information, we can help design a personalized treatment plan.
Get an Accurate Diagnosis Through Allergy Testing
Skin Allergy Test
In many cases, an allergy skin test is the best way to diagnose an allergy. These tests use diluted extracts from various allergens — such as dust mites, pollen, food or venom — that are commonly found in our local area.
A small scratch is made into the top layer of the skin using a specific allergen. With a positive allergic reaction, a small, raised, reddened area (called a wheal) with a surrounding flush (called a flare) will appear at the test site. The size of the wheal gives your Lahey physician an important clue for the diagnosis.
Patients scheduled for a skin allergy test should review these instructions on how to prepare. These instructions also tell you what to expect during testing and which medicines, including antihistamines, to stop before the test. If you have chronic hives and use antihistamines daily, you do not need to stop the antihistamines before your appointment.
Allergy Blood Test
In some instances, allergy skin testing cannot be performed. Another option is advanced allergy lab tests with a blood sample from the patient. Allergy blood tests measure how much immunoglobulin E (IgE) antibody your body makes when exposed to a particular allergen.
Finding a Clear Path Forward
Once we have the results of your allergy testing, we can make an accurate diagnosis. Your allergist will discuss the results with you and find the best treatment option for you to get allergy relief.
